- Alibre https://www.alibre.com/ (note that there is a CAM option which is a re-badged MeshCAM)
- Moment of Inspiration 3D https://moi3d.com/ (this is probably the next commercial package I try)
and of course FreeCAD has a CAM Workbench which has seen great strides and Solvespace has a basic facility for G-code generation and some folks just program G-code/CAM directly --- I've been working on a tool for that myself: https://github.com/WillAdams/gcodepreview
Can it be locally installed in docker or something? It's kinda a bummer when I need to do something and there's a connection problem or the server is down.
In fact I had that only a month or 2 ago with fusion 360. Something in their cloud was down so I couldn't export to STL and i really needed that urgently.
KiCAD has pretty awful UX though. I've tried all of the FOSS PCB design apps except LibrePCB (on my to-do list) and Horizon EDA is definitely the one I'd recommend (even though it also has a fair amount of UX oddities it's much better than KiCAD).
DesignSpark PCB is also decent - only minor UX mistakes like warping the mouse when you zoom.
It's not perfect but it's pretty damn good these days. By EE standards it's positively awesome. Single platform vendor toolchain hell is why people leave commercial software and move to KiCad, which runs everywhere, is open source, and has a plugin architecture plus mostly every feature you could ever need except high end simulation (which just needs time).
Has anyone tried EasyEDA? I hear people raving about it, but I don't know if it's because of the tight integration with LCSC, the availability of symbols and footprints, or if it's really that good.
EasyEDA is basically a single-supply-chain web-SaaS alternative to open source multi-platform KiCad. Not a smart thing to invest time in. Furthermore, its design library is of worse than dubious quality. The vast majority of shared designs are probably non-functional to dangerous.
Worst case, you can draw custom footprints pretty easily.
AI is good but it tends to fall down when it comes to multiple conflicting design constraints, supply chain conditions, thermal considerations, mechanical considerations, and other concerns which are not same-domain as an electronic connectivity topology problem. Let's not get started on environmental factors, firmware hacks, board house physics, or assembly labor optimization.
second KiCad. just had my first board printed a few months back. its an esp32 stackable daughterboard. first time doing anything like that outside of breadboarding, and it worked great.
- 100% free, no subscriptions, no accounts, no cloud
- Local-first: all slicing and toolpath generation runs on your machine
- Works in any browser, even offline once loaded
YES!
I think a new type of open source is emerging centering around what is now possible in browsers. Browsers have a great track record when running legacy projects. Relying on a backend could be a liability for longevity.
I built opal editor myself, a local first open source free markdown editor with these same principles, https://github.com/rbbydotdev/opal
That's an interesting take. I've never really thought of it that way before, but I think you are right that you'll have an easier task running an HTML file with embedded JavaScript from 15+ years ago in a browser than running a 15+ year old binary.
That, my friend, is not how offline works.
You will be required to have internet access in one way or another.
Offline works 100% locally no matter if you have internet or not.
But you have to get the software somehow? Once you get it, it works offline. The same here I guess: once you download the source code/binaries into browser's cache (that can store things indefinitely) it's offline.
Umm, I’m confused about this comment… the concept of a web app that gets saved into browser cache and then can be loaded and used while offline definitely isn’t new. See Photopea etc
With a stand-alone application once you download it in your file system you know exactly where it is and how to create backups etc.
A "browser cache" is just an opaque bit of storage. What if you need to update/reinstall your browser or want to switch? I wouldn't trust important data to it.
I generally feel uncomfortable how so many applications are browser-only these days. The thought of having important data in a tab that you might close by mistake at any moment is uncomfortable.
Browsers should really only be used for fleeting content, not productive work.
probably adaptive milling, which will be in an upcoming release. sharp path changes in harder metals can wear or break tools if you don't go slow, which has other issues.
no shared lineage. Cura and Kiri started around the same time (2011/2012), but as completely separate projects. Cura is a C++ desktop app and Kiri has always been 100% browser-based (no cloud, all computation in the browser sandbox). the licenses are different, too. Cura/Prusa/Orca are GPL based and Kiri is MIT.
OT: Why is that Alphabet, Mozilla, Apple, etc can get together to create web standards that allow anyone to create software that works cross-platform - only a browser is needed, but Microsoft, Alphabet, Apple, Canonical, etc can't get together to create standards that allow anyone to create software that works cross-platform?
The browser is an extremely poor medium to deliver applications. It works, but barely, is a huge resource hog, fragile and it breaks way too often due to a lack of backwards compatibility between browser versions of the same manufacturer. I have a small app that I support and it's been fun to get it to work in the browser (instant cross platform support was indeed the driver) but the experience is still sub-par compared to what I could do on a local application.
Unfortunately, I think all these things are externalities - or at least, areas that don't impact revenue enough to get companies to change.
I too wish that software would be efficient, robust and long-lasting. But it seems that most people don't care about this enough (compared to other factors) to force change. (Alternatively, they are locked in to platforms they don't like to use.)
this does not track with my experience, so possibly it's the nature of your app or the way it's coded. frameworks like react are notoriously crap. stick to pure html5/css/js and it can be extremely fast and light.
You could have clicked on my profile to find the app that you're criticizing unfairly. It does not use react, but it uses pure html5,css,js, it is extremely fast and light. And yet, there are things that it can not do simply because it runs in the browser, which is a poor operating system for a hard real time program to run under.
I did not criticize your app. I offered that your blanket statement that "The browser is an extremely poor medium to deliver applications" does not comport with my experience. And it looks like I nailed it, too. It is the nature of your application. Had you said "the browser does not offer a real time API which I need for my application", there would have been nothing to say. This is obviously true. Even native desktop apps provide an inadequate environment for "hard RT". So I suspect that is also not a true requirement, either.
Well, there are apps that you can only do native, not in a browser, we agree on that. But I also think that the browser is actually providing a very compelling standard OS with batteries included for many kinds of applications, and now there is even webGPU. I am currently building a local-first interactive theorem prover with built-in IDE as a PWA, in TypeScript, and you have really cool tools you can use as a foundation for something like this, such as ProseMirror and IndexedDB. Of course the raw prover can also be run from the command line via node. Claude Code is also very useful in this environment. Yes, different browsers are an issue, but so much works on all modern ones.
Apple make money from the App Store and from selling their hardware, so why should they want to invest on something that let people install software bypassing the App Store or that works on other platforms?
Alphabet make money from ads, so they want web pages, apps on Android and Chrome everywhere.
Mozilla make money from Google.
Microsoft make money from software licenses and subscriptions and from cloud services. They might be interested in cross platform installation.
At the moment what we have is PWA and WASM and icons on the desktop.
There are many projects that try to make cross-platform mobile apps easier, including Google's own Flutter. I haven't heard of them getting much cooperation from the teams working on Android or iOS, though.
At least for stuff that doesn't use device API's much, it seems like websites are the way to go. They're a whole lot easier to build than mobile apps.
The API surface becomes the lowest common denominator of all the platforms it supports, possibly with a path to support platform-native features, but probably in a way that’s necessarily not as good as native.
I think we already have plenty of avenue in ‘solutions’ like Electron to let people build bad apps.
The boring answer from Capt. Obvious. Incentive alignment.
That said, WebAssembly might be the trojan horse. While it started as a browser compile target, WebAssembly System Interface (WASI) is extending it beyond browsers into filesystem, networking, etc. etc. etc.
Fingers crossed, we may get cross-platform standards by accident.
this. webkit is intentionally hobbled and years behind the standards. browsers on iOS are forced to use webkit for ginned up security excuses/reasons so that no real browsers that implement full standards can complete with heavily taxed app store spyware.
Am I weird in not being too surprised? It don't have experience with wire EDM but every toolpath generator or slicer I've ever used was just local software.
Truly. The slicer is able to generate bugs I've never seen before, in around 6 years of printing with several slicers and firmwares. Cura, Flashprint, Orca, Prusa, using Marlin, Sailfish, Klipper. None of them produced the weird stuff I find with Bambu's pipeline.
When the bugs don't creep up it's absolutely incredible, though.
The slicer even introduces bugs in things that were working perfectly in the software they ripped off.
For the A1 and P1S you're better off backporting the profile to PrusaSlicer or Orca.
And don't get me started on the network plug-in (the lack of transparency there makes me fairly suspicious that something is up) and the lack of directory structure support on the SD cards. Really, how could you mess it up.
It’s a fork of PrusaSlicer, which was a fork of Slic3r. There’s a fork of BambuStudio called OrcaSlicer now.
They didn’t “rip off” an open source project, they forked it just as the parent project forked another project. This is how open source is supposed to work, isn’t it? Why are we shaming them for doing the thing we always encourage and then giving features back to the community which have gone into OrcaSlicer now?
If you’ve got more information then just say it. Being snide and alluding to some information you’re not sharing isn’t helpful at all.
I’m not lecturing anyone. I was trying to leave a helpful comment for the thread to clarify that it’s a fork, just like the fork that it came from, and the other slicer that was forked from it.
They release their stuff, but only under (significant) community pressure, and they try to do it in such a way that interop becomes harder and harder. Some parts they never release, because 'reasons', but are suspected of containing large chunks of FOSS used outside of license. They release breaking updates that lock out other applications from interfacing with their hardware.
Bambu is fantastic hardware but they're doing the exact same thing that DJI did in the drones field. A few more years and Prusa will have gone under, because it is impossible to compete with Chinese state subsidized companies whose sole purpose it is to dominate a market where they take something that has been community built and then embrace and extend it in every way possible to kick the door shut behind them. All of course in your best interests.
Also what's weird is that this project seems to be primarily written in javascript. I can't imagine that's a pleasant user experience for generating tool paths...
it's a combination of JS, WASM, and WebGPU. the JIT engines are so much faster than you would imagine, especially if you tune your code right. workers allow for parallel processing on all of your CPU cores. WebGPU, at least in Chrome, is kind of amazing.
For those wondering why having a browser based slicer is useful: teaching. The site mentions this, but I'll add my own experience that having good in-browser software like this is incredibly useful when you have a classroom full of students who a) aren't used to installing desktop software, b) are running a bunch of different operating systems (including chrome os), and c) have firewalls prevents them from installing local software anyway.
I wouldn't want online tools to be come the default (like google docs) but having them as an options is great. (I find onshape and photopea useful in this way as well).
A fun thing you can do with this excellent sw is to slice a 3d object into slices to cut with a laser cutter. Ie you'll get a bunch of layers of eg cardboard or plywood, which you can assemble into a large object. Increase layer height to thicker than your material to create gaps in between. This operation is the basis for some very nice looking creative stuff you can find on etsy or even high-end wood working stuff.
Part of me wants to be wary. The useful life of industrial machinery such as CNC mills is much longer than the lifespan of websites, so locally-installed software you own is usually a better choice.
But another part of me realizes that everyone is using Fusion360, despite the fact they have a history of taking away features to force people to migrate to paid tiers. So it probably doesn't matter.
But browsers (and browser technologies) have documented track of being fully backward compatible up to the beginnings of WWW, and it's not going to change.
Which actually is much much better than any other environment you can imagine - unless of course you use (and want to use) that one frozen in time 25 year old PC. And pray nothing breaks (y2k bugs and whatnot).
If the software is open source (and works offline) you can have it functional in 10 or 20 more years. And it will be "locally-installed software you own" you want.
> But browsers (and browser technologies) have documented track of being fully backward compatible up to the beginnings of WWW, and it's not going to change.
That can however be undermined if web apps are poorly built and depend on quirks and behaviors specific to a particular engine (or in some cases, even particular versions of a particular engine) in order to function.
So I would say this benefit applies specifically to web apps that thoroughly apply KISS — that is, using only the most boring, solidified, widely supported APIs and favoring robustness over bells and whistles — and make a point of testing against all three major engines. Those apps will likely stand the test of time and run even under future new engines. On the other hand, the ones with severe shiny API syndrome that only ever get tested against the latest Chrome are probably much more brittle and more likely to be broken N years after abandonment.
"Fully backwards compatible" isn't really true, and even if it were, then you're stuck using browser-based software and its myriad of inherent downsides.
People (generally) use web-based apps that are good enough in spite of the web stack -- not because of it.
For comparison, I was looking at slicer source lately. Slic3r and its popular forks (prusa slicer, Bambu, orca) are using C++ with wxWidgets and boost. Sometimes outdated versions of those libraries at that. But stuff that will work, and totally local.
I have a CNC mill made in 2006. It's still perfectly fine. It should still be fine in 2036. The most significant threat to its existence is the compatibility of OS drivers and software support in CAM tools. That and USB ports getting replaced by something else, which was a problem for earlier-generation machines that used RS-232.
Great tool for a Makerspace - really appreciate the ability to use the same tool for laser cutting, 3d printing, and CNC. These are big jumps for people typically - having a familiar tool would help people transition from one area to another.
Makerspaces and education are two areas of focus. no SW install, fully loads in under a second. through the Onshape integration and ability to run on Chromebooks, it's made its way into high school and university STEM curriculum.
This looks great. I was hoping it would have been a good OrcaSlicer replacement for my FDM printer, but unfortunately it didn't generate any top surfaces (except for the topmost one) for a model I imported in. I didn't know if it was the printer profile (Creality.Ender3) or something else, but it seems I'm still using OrcaSlicer for the time being.
there are desktop builds https://grid.space/downloads.html that run entirely offline. you can also use the center menu to "install" it as a progressive web app.
It says 'local first' doesn't that mean you can run it locally after downloading? That's how I set up pianojacq, just so there aren't going to be a lot of disappointed people that lose their practice logs if I get hit by bus #9.
I bought a bambu p1s recently and it can be used entirely offline.
You can import models to orcaslicer (open source), do your slicing, and export the g code file to SD card.
If you want to skip the SD card, block the printer's mac/ip address at the firewall and set up WiFi. Then send the print directly from orcaslicer.
That being said, my gut says bambu is going to slowly require a persistent connection to the cloud at some point. Maybe they think they are an EV car company.
Yes, you can use the P1S offline, but they've done everything possible to make it hard: crappy micro sd interface without the ability to use folders, USB plug absolutely inaccessible (see if you can even find it) and then, once you've found it it turns out that there is absolutely no way to use it to print with. They push you towards their closed source plugin 'for your benefit'. Fuck that stuff. There is absolutely no way I'm going to run a Chinese built piece of software that I can not inspect on my desktop. FOSS or bust.
I'm curious - which firmware version are you on? Just yesterday I got confused when I accidentally entered the "cache" folder (Handy sliced models?) on my P1S, so it looks like my machine definitely supports folders at least. I am located in the UK and bought it late 2025.
AFAIK, the hidden internal USB port is intended to charge a phone/other device used as a "touch controller".
I don't like their closed-source control and the way they've managed local integrations, but I also want to accelerate making things with a printer that just "prints" (akin to how some will buy into the Apple ecosystem for something that "just works"). I've now sold my previous open-source Klipper/Mainsail printer which I heavily modified.
If/when Bambu makes their ecosystem unbearable for me, I will switch away (probably to a Prusa). For now, the ease of use of the machine has led to much more things being made as I can trust it to work accurately and reliably.
Yes, this is the dilemma right now. I have 30+ prusa's and 43 Bambu's and another dozen or so K1s. They all have their quirks, weaknesses and strong sides but for sheer reliability and volume you can't beat the Bambus. But for development work I'd much rather have the oldest bedslinger that I have because it is so incredibly precise, even if it is terribly slow as well. K1 I would not recommend for anything, too fragile and too irregular from one machine to another, each is a different printer. To get to that level of lack of consistency must have taken some real thinking.
I'm not so sure. You've had people insisting that, or how they'll lock it to only their own NFC tagged filaments but lets be real, if they start imposing serious restrictions most purchases would go to other makers.
They make solid enough devices sure, but they dont exactly have a moat that would keep users buying their stuff if it were to start getting locked down. They have far more to lose than they have to gain doing so.
I work with the Smoothieware project. The V1 Smoothieboard was one of the first with ethernet onboard (although kinda borked).
First thing that was advised to everyone was "never connect this to anything outside your local network"
Nowadays...it seems that warning has been lost. Even in the face of firmware updates that caused physical damage.
Something to be said for building your own printer.
Elegoo printers can be offline - you can run everything from the machine itself, as long as you have your model/s on a thumb drive. Or is that not what you mean?
These people are so ridiculous. It'll fail on 1A and 2A grounds, not to mention challenges implicit from 4A and 5A considerations. They can't ban arbitrary information, even dangerous information, and there's a presumption of regularity - you're presumed innocent of wrongdoing absent evidence, so they can't legislate the assumption of criminality by default. They can't ban private creation of firearms and weapons, so long as other aspects of the law are being followed. They can't assert control over private property and mandate being online, this is equivalent to a warrantless search of private home activity. Arbitrary compliance costs and increased prices can amount to violations of 5A takings clause, and you can't bake in a violation of your right to refuse to incriminate yourself, especially with the vague, subjective nature of the proposed legislation. There's also 5A due process concerns, with the legislation being overbroad and arbitrary. 14A presents equal protections and lays the basis for discrimination between hobbyists and manufacturers and interstate commerce concerns.
The whole notion is about as anti-American and authoritarian as laws get, I don't see it as anything more than political grandstanding, and even if Washington passes it with statewide, unanimous endorsement, it won't last a year before 9th circuit court strikes it down on purely 2A grounds.
Washington state lawmakers, led by Democrats, have introduced bills like HB 2320 and HB 2321. HB 2320 is sponsored solely by Rep. Osman Salahuddin (D-48th District), focusing on prohibiting 3D printers and CNC machines for untraceable firearms. HB 2321, pushing printer DRM requirements, similarly lacks Republican co-sponsors based on available details. In Washington where this is going on in the state House Democrats hold 59 seats, Republicans hold 39 seats and in the state Senate Democrats hold 30 seats, Republicans hold 19 seats. These Democrat-sponsored bills passed initial House committees along party lines, with no Republican co-sponsors or primary support
Virginia Democrats are advancing multiple gun ban bills in the 2026 session, including assault weapon sales bans and magazine capacity limits, primarily through Democrat-controlled committees. Virginia's General Assembly has a slim Democratic majority sponsoring and pushing these measures without Republican support.
Bills like house SB 217 (assault weapon ban) and HB 271 (semi-auto ban) were approved in the Democrat-led Senate Courts of Justice Committee strictly along party lines. Sponsors such as Sen. Saddam Azlan Salim (D) lead these efforts, facing opposition from Republicans like Del. Terry Kilgore (R). They await full Assembly votes and signature from Democratic Gov. Abigail Spanberger.
In NY State, Democrats, holding supermajorities in the Assembly (103-47) and Senate (42-20), champion Governor Hochul's 2026 State of the State proposals. These include criminalizing unlicensed possession/sale of CAD files for 3D-printed guns (via Penal Law amendments), mandating 3D printer safety standards to block firearm production, and requiring recovery reports to state police. Key bills like S.227A (Sen. Hoylman-Sigal, active in 2025 session) target 3D-printed ghost guns/silencers as felonies; related A2228 pushes printer background checks.
Republicans offer no sponsorship or support, labeling Hochul's agenda and bills like S.227A "anti-gun, anti-speech" infringements on Second Amendment rights and innovation for non-gun printing. NRA-ILA criticizes them as futile against criminals while burdening hobbyists
In my opinion the ICE unrest is a smoke screen. There is a separate fully frontal assault on personal liberties impacting normal American citizens happening right now and it is happening while all the attention is on Minneapolis!
At the same time it's neat to live in a separated reality from the people thinking that "In my opinion the ICE unrest is a smoke screen."
The federal gov disarmed a protestor and executed them on the street.
That doesn't seem like a "distraction"... that seems like -the literal thing that you're worrying about- happening in a highly obvious and direct way.
As a left-wing gun owner, a pretty common conversation is about how limited the right wing gun owners understandings are, because this is, like, literally the thing they have been fantasizing about all along.
Wild times for sure.
I hope the world many of us live in never actually enters yours and you can keep enjoying your fantasy of government oppression while some of us are out here being physically assaulted by the state.
> The federal gov disarmed a protestor and executed them on the street.
He was shot after disobeying lawful orders and the man who disarmed him possibly negligently discharged the victim's firearm while the other officers were wrestling him and the other officers didn't have the information that he was disarmed. This wasn't intentional, this was an accident. There is also another angle showing him kicking an ICE vehicle and breaking its tail light the week before. This is no bystander. It is delusional to believe that it is possible to deport millions of convicted criminal illegal aliens without an incident while thousands interfere with police operations as they deport criminals. The bills being passed are far more relevant to Americans' civil liberties because they make the average American who is NOT currently a criminal into one for possession and manufacture of plastic and metal parts. This is an untenable position.
> some of us are out here being physically assaulted by the state
Yeah, I'm not belligerently protesting the deportation of illegal aliens.
He was shot while being dog piled by 6 officers dude. There was no way for him to defend himself when they already had taken his weapon. It was murder. Was he intentionally out there protesting? Yeah, he probably was. Was he filming ICE and giving them verbal hell? Absolutely he was. Was he interfering? He absolutely wasn’t. They just let him get under their skin because they aren’t professional. They murdered him because they got scared that he had a gun. One of the officers was on video saying “I got the gun…” sighing as he stood up.
So yeah, tensions are high. Minnesotans feel violated. ICE sees a battleground, not a state. That’s an issue.
”There's a reason you separate military and the police. One fights the enemies of the state, the other serves and protects the people. When the military becomes both, then the enemies of the state tend to become the people” - Admiral Adama
Same video, two movies. Presentation, pace, timing, narrative all designed to reinforce your existing biases, even if you aren't aware of them. You look and think you've seen. You're nudged and put into a bubble with people offering up comments that validate and verify what you think, and what you know, and what you believe.
Anything outside your bubble is framed as a conspiracy theory or the ramblings of deluded, even evil people on "the other side".
The media streams you watch end up being a rorschach test - carefully crafted and deployed to different bubbles, A/B tested, cynically manipulative and deliberately framed and intended to evoke specific reactions. The language is carefully used so two people can watch the exact same clip or newscast or soundbite and hear what sounds like a reasonable reinforcement of what they already believe. Sometimes things will even technically be 100% factual, but it'll be just as manipulative and as much of a "lie" as if they'd made it up entirely.
I don't think bubbles is the right paradigm, anymore - these are deep, deep pits, and every piece of media that reinforces your model, where that model is the one intended for you to have by some of the big influences, brings you another shovelful deeper, and you've got to put that much more effort in to dig your way out.
Trying to talk to anyone who hasn't worked their own way out of digging out of a media pit ends up being a team sport or a tribalistic conflict - the facts and the stories don't mesh, and if you're 100% certain of your facts, and your "opposition" concedes to the facts, then you're going to think your story is the right one. The cognitive dissonance and the effort required to update your model to match reality - to recognize the manipulative, malignant influences deploying these conflicting storylines, and to figure out how to identify what actual reality is - is too much for most people, and way too much for any casual online interactions.
Not sure how you fix that without forbidding some actors from doing what they do at a legislative level, and that gets into hairy freedom of speech territory.
You saw a video that might have been murder. It might have been an accident. We know the gun he carried was notorious for unintended discharge. It might have been dropped and gone off, it might have fired accidentally in the agent's hand after being taken away, prompting the trained, legitimate response of law enforcement. It could have been a cold, deliberate execution if one of the CBP agents knew Pretti from previous conflicts and was antagonistic towards him. It could have been a heated, spur of the moment killing way outside the bounds of the law.
You certainly don't know - none of us have all the facts, and the investigation into it will reveal it. It's that both sides present the same facts, the same video, and tell two starkly different narratives, either of which are reasonable conclusions based on the facts that can be proven from the available evidence. What doesn't get talked about is that even with multiple videos, from multiple angles, nobody has sufficient evidence to definitively prove what actually happened.
What I do know is that it's extraordinarily stupid to get into a heated conflict with any sort of law enforcement, especially when armed, because any sort of accident or exceptional circumstance or misinterpretation of events is not going to go your way, legally and sometimes with regards to you losing your life. Pretti was in the wrong - you cannot physically interfere with and antagonize federal law enforcement. We have legal remedies to hold officers to account for overstepping or violations. He was well within his rights to record and then report the mistreatment of the woman he was stepping in to "protect", and the proper place and time to remedy that wrong is in court. If the officer was in the wrong, he'd have been held to account. Getting physical and up in the officers face and space was either stupid and ignorant, or a deliberate act intended to elicit additional violence. There's protest "training" out there that teaches people to do that sort of thing, with the intent of escalating violence deliberately, specifically for agitprop and convenient political narrative purposes.
The government has the sole and absolute monopoly on violence, for better or worse, and if you intrude on that in the slightest, you will lose.
They want the nebulous, uncertain, rorschach test incidents where they can spin an event to tell the story they want to tell, regardless of whether that story is actually true. That doesn't mean the CBP agents were in the right, nor that Pretti was responsible or did it on purpose, or that anyone involved in the whole series of events had ulterior motives. The only thing we know, until an investigation is finalized, and due process is enacted, is that we lack critical information that explains the full context and nuance of the incident. There are a metric shit ton of ways the actual story might have gone, ranging from schizophrenic break (by an agent, or Pretti) to suicide by cop, to tragic accident caused by a notoriously flawed weapon, to some other asshat, currently unknown, throwing a firecracker after the officer announced "gun", and so on. We don't even have enough information to know what's a "likely" outcome and make some reasonable Bayesian projections.
The videos we saw aren't proof of anything. They're evidence of dozens of different possible scenarios, with a wide range of likely possibilities, and dozens more we don't even know to consider without having the information that investigation will bring to bear.
Hoss, you can rashomon yourself into any position.
That tactic is almost always an excuse to not realize some hard truth about the world.
Most of us look at your position and understanding you're literally just trying to gaslight yourself.
The kind of radical moral relativism indicated by your position was appealing to me when I was a sophomore philosophy student, in the same way that I found solipsism to be an interesting idea to entertain.
For instance, you know for a fact that "The government has the sole and absolute monopoly on violence" is a) not true, and as the gov becomes ever more violent it's not even "legitimate", which is the word you've gaslighted yourself into forgetting in your thinking here.
But I'm an adult now, and I have spent enough time questioning my beliefs. I have been around enough folks who think they are rational but who haven't done the "work" that I can smell it when I do it, and I can smell it when other folks do it.
They are just stupid. The WA state has a problem with a growing number of shootings, so the reps need to show that they are "doing something".
Meanwhile, the legal system in WA requires 5 (five) arrests for juveniles to be given _any_ jail time for gun crimes. And the laws regarding the unlawful possession of a weapon are almost completely unenforced.
Sigh. I'm pretty pro-gun-regulation, but I just can't stand our legislators' furious virtue signaling.
This reminds me of William Gibson's "The Peripheral" in which the protagonist runs a rural 3D print shop where everything has to be licensed and government approved. We live in the near future.
Bleh, just wire into the steppers and extruder directly, not that hard.
To be clear I have no desire to print firearms but I do not want my tools online and getting bricked when the company who made it goes out of business.
I don’t think a company should have a say in what you do with their product after you have purchased it. Whether you intend to print firearms or not. The acts of the few should not withhold liberty of the many.
They'll just run it through BigBrotherGPT, a CAD aware multimodal censorship bot specially trained to recognize Bad Things that must not be printed. And while this is sarcastic, it also occurs to me that it's also really, really achievable. OpenAI could probably whip one up in a weekend office hackathon.
I doubt it's actually achievable without either either a massive false positive rate or massive false negative rate.
Last I looked, the vast, vast majority of 3D printed firearms were basically just printing the receiver (the part that the government considers "the gun") which is more cosmetic than functional. It holds parts, but isn't pressure-bearing, the firing pin isn't attached to it, etc, etc. Like [1] is the part of a Glock that gets stamped, and you could trivially change every part of that except where the mag goes. You could move the mag button, you could add the slide for the upper afterwards (and would want to anyways, so it can be metal). You could also print snap-off plates over the holes so it looks solid.
I would wager humans would struggle with this given that the people designing the models are actively trying to hide what it is. This is a dedicated community, not really the casual "I'll do it if it's easy" crowd, because it's currently not super simple and easy.
That’s the tricky part of this whole mess. Online servers would have to mesh and volume your model and determine if it matches a likeness of any known models. So much for printing NERF.
I don’t think this will pass as is but it shows you where lawmakers heads are. They would rather brick your capability than do actual policing.
What gets me is this doesn’t even seem to be the most effective way to regulate this. 3D printed guns require a lot of non 3D printed gun parts. You can’t 3D print bullets for example.
The is really just a US specific issue where 90% what you need for a gun can be purchased easily, but the non functional handle requires registration, etc.
They could just make buying gun parts as strict as buying a whole gun
And work really well until you have more than 20 files or so after which it becomes impossible to manage the SD. Your best bet here is to have a stack of SDs of what you'd normally put in folders. Really nice, especially given how easy it is to write on the outside of a micro-sd what the contents are.
Surprised this hasn't been shared here before.

What caught my attention:
- 100% free, no subscriptions, no accounts, no cloud
- Local-first: all slicing and toolpath generation runs on your machine
- Works in any browser, even offline once loaded
- Supports FDM/SLA, CNC milling, laser cutting, wire EDM
- Fully open source: github.com/GridSpace/grid-apps
Refreshing to see a tool that isn't trying to lock you into a subscription or harvest your data.
(ob. discl., I work for a company which sells software in this space)
I wrote up a bit on Carbide Create at:
- https://willadams.gitbook.io/design-into-3d/2d-drawing (note that there is a link to a free (as in beer) download for Windows or Mac OS at that link)
- https://willadams.gitbook.io/design-into-3d/toolpaths
Other commercial programs which one licenses and installs and which don't intrude beyond that include:
- MeshCAM https://www.grzsoftware.com/
- Alibre https://www.alibre.com/ (note that there is a CAM option which is a re-badged MeshCAM)
- Moment of Inspiration 3D https://moi3d.com/ (this is probably the next commercial package I try)
and of course FreeCAD has a CAM Workbench which has seen great strides and Solvespace has a basic facility for G-code generation and some folks just program G-code/CAM directly --- I've been working on a tool for that myself: https://github.com/WillAdams/gcodepreview
Can it be locally installed in docker or something? It's kinda a bummer when I need to do something and there's a connection problem or the server is down.
Edit: looks like yes! https://github.com/GridSpace/grid-apps I will try it then.
In fact I had that only a month or 2 ago with fusion 360. Something in their cloud was down so I couldn't export to STL and i really needed that urgently.
Any circuit designers? looking to hobby, but what I saw was all proprietary
You mean like PCBs? KiCad is pretty popular.
KiCAD has pretty awful UX though. I've tried all of the FOSS PCB design apps except LibrePCB (on my to-do list) and Horizon EDA is definitely the one I'd recommend (even though it also has a fair amount of UX oddities it's much better than KiCAD).
DesignSpark PCB is also decent - only minor UX mistakes like warping the mouse when you zoom.
KiCAD has pretty awful UX though
It's not perfect but it's pretty damn good these days. By EE standards it's positively awesome. Single platform vendor toolchain hell is why people leave commercial software and move to KiCad, which runs everywhere, is open source, and has a plugin architecture plus mostly every feature you could ever need except high end simulation (which just needs time).
Has anyone tried EasyEDA? I hear people raving about it, but I don't know if it's because of the tight integration with LCSC, the availability of symbols and footprints, or if it's really that good.
EasyEDA is basically a single-supply-chain web-SaaS alternative to open source multi-platform KiCad. Not a smart thing to invest time in. Furthermore, its design library is of worse than dubious quality. The vast majority of shared designs are probably non-functional to dangerous.
Ok, but it is easy to drag and drop components from lcsc. Sounds like an enormous time saver. But you're probably right about the lock-in.
Anyway, I'm waiting for AI that is smart enough to read a datasheet and convert it to a KiCad symbol and footprint. Should be around the corner.
Common components all have symbols in the KiCad standard libraries.
For others, just use https://github.com/Steffen-W/Import-LIB-KiCad-Plugin or similar to import from an online source. Also grabs 3D models.
Worst case, you can draw custom footprints pretty easily.
AI is good but it tends to fall down when it comes to multiple conflicting design constraints, supply chain conditions, thermal considerations, mechanical considerations, and other concerns which are not same-domain as an electronic connectivity topology problem. Let's not get started on environmental factors, firmware hacks, board house physics, or assembly labor optimization.
Eye of the beholder, I suppose. I like KiCAD's UI much more than Altium (but to be fair, I hate Altium).
Kicad is great. If you don't like the UI then you haven't used it enough.
second KiCad. just had my first board printed a few months back. its an esp32 stackable daughterboard. first time doing anything like that outside of breadboarding, and it worked great.
Creating PCBs is surprisingly straightforward and there are a ton of good resources available.
It’s probably one of the few area of YouTube that is actually still useful. Probably a high enough barrier to entry to stop most slop.

YES!
I think a new type of open source is emerging centering around what is now possible in browsers. Browsers have a great track record when running legacy projects. Relying on a backend could be a liability for longevity.
I built opal editor myself, a local first open source free markdown editor with these same principles, https://github.com/rbbydotdev/opal
That's an interesting take. I've never really thought of it that way before, but I think you are right that you'll have an easier task running an HTML file with embedded JavaScript from 15+ years ago in a browser than running a 15+ year old binary.
> Works in any browser, even offline once loaded
That, my friend, is not how offline works. You will be required to have internet access in one way or another. Offline works 100% locally no matter if you have internet or not.
But you have to get the software somehow? Once you get it, it works offline. The same here I guess: once you download the source code/binaries into browser's cache (that can store things indefinitely) it's offline.
True, but you are at the whims of the browser cache, and how long it wants to keep it around.
If you are worried, download and self host. As suggested on the website (when discussing trust and PII).
> But you have to get the software somehow?
We call this: download. Usually better than RCE.
You're misunderstanding how websites work. You can install it locally on your computer and run it via localhost https://github.com/GridSpace/grid-apps
There's an electron build, although why you'd use it over a native slicer is beyond me.
Umm, I’m confused about this comment… the concept of a web app that gets saved into browser cache and then can be loaded and used while offline definitely isn’t new. See Photopea etc
With a stand-alone application once you download it in your file system you know exactly where it is and how to create backups etc.
A "browser cache" is just an opaque bit of storage. What if you need to update/reinstall your browser or want to switch? I wouldn't trust important data to it.
I generally feel uncomfortable how so many applications are browser-only these days. The thought of having important data in a tab that you might close by mistake at any moment is uncomfortable. Browsers should really only be used for fleeting content, not productive work.
That used to be the case, but there’s a new API worth checking out, you can read and write files right on your computer https://developer.mozilla.org/en-US/docs/Web/API/File_System...
I've used kiri:moto for several simple CNC projects!
This probably won't scroll to the correct place on the page but there's some images of my project at https://hcc.haus/propmania/#2024-palm-torches and https://static.cloudygo.com/static/Prop%20Making/2024%20Palm...
I used it instead of the terrible closed source Easel App for a CARVEY hobby CNC. For metal milling I find Fusion 360 is necessary.
Curious if you can elaborate on what's missing or failing, to require Fusion 360?
probably adaptive milling, which will be in an upcoming release. sharp path changes in harder metals can wear or break tools if you don't go slow, which has other issues.
More open source, browser-accessible tools is a good thing.
That said, aren't Prusa/Orca/etc. all already open-source (and part of the same lineage)?
no shared lineage. Cura and Kiri started around the same time (2011/2012), but as completely separate projects. Cura is a C++ desktop app and Kiri has always been 100% browser-based (no cloud, all computation in the browser sandbox). the licenses are different, too. Cura/Prusa/Orca are GPL based and Kiri is MIT.
I'm not talking about Kiri; I'm talking about the mainstream derivatives of Slic3r.
Yes, Slic3r -> Prusa Slicer -> Bambu Studio -> Orca Slicer.
Many "official" slicers (Elegoo, Creality, Anycubic, and I imagine others) derive from Orca.
OT: Why is that Alphabet, Mozilla, Apple, etc can get together to create web standards that allow anyone to create software that works cross-platform - only a browser is needed, but Microsoft, Alphabet, Apple, Canonical, etc can't get together to create standards that allow anyone to create software that works cross-platform?
You answered the question yourself: There is already a standard that allows anyone to create software that works cross-platform: the browser.
The browser is an extremely poor medium to deliver applications. It works, but barely, is a huge resource hog, fragile and it breaks way too often due to a lack of backwards compatibility between browser versions of the same manufacturer. I have a small app that I support and it's been fun to get it to work in the browser (instant cross platform support was indeed the driver) but the experience is still sub-par compared to what I could do on a local application.
Unfortunately, I think all these things are externalities - or at least, areas that don't impact revenue enough to get companies to change.
I too wish that software would be efficient, robust and long-lasting. But it seems that most people don't care about this enough (compared to other factors) to force change. (Alternatively, they are locked in to platforms they don't like to use.)
this does not track with my experience, so possibly it's the nature of your app or the way it's coded. frameworks like react are notoriously crap. stick to pure html5/css/js and it can be extremely fast and light.
You could have clicked on my profile to find the app that you're criticizing unfairly. It does not use react, but it uses pure html5,css,js, it is extremely fast and light. And yet, there are things that it can not do simply because it runs in the browser, which is a poor operating system for a hard real time program to run under.
I did not criticize your app. I offered that your blanket statement that "The browser is an extremely poor medium to deliver applications" does not comport with my experience. And it looks like I nailed it, too. It is the nature of your application. Had you said "the browser does not offer a real time API which I need for my application", there would have been nothing to say. This is obviously true. Even native desktop apps provide an inadequate environment for "hard RT". So I suspect that is also not a true requirement, either.
Ah, the true Scotsman version of 'not that kind of app'.
Well, there are apps that you can only do native, not in a browser, we agree on that. But I also think that the browser is actually providing a very compelling standard OS with batteries included for many kinds of applications, and now there is even webGPU. I am currently building a local-first interactive theorem prover with built-in IDE as a PWA, in TypeScript, and you have really cool tools you can use as a foundation for something like this, such as ProseMirror and IndexedDB. Of course the raw prover can also be run from the command line via node. Claude Code is also very useful in this environment. Yes, different browsers are an issue, but so much works on all modern ones.
> There is already a standard that allows anyone to create software that works cross-platform: the browser.
Which one exactly ? IE ? Dillo ? Lynx ? Pale Moon ? Firefox version 126 ?
Apple make money from the App Store and from selling their hardware, so why should they want to invest on something that let people install software bypassing the App Store or that works on other platforms?
Alphabet make money from ads, so they want web pages, apps on Android and Chrome everywhere.
Mozilla make money from Google.
Microsoft make money from software licenses and subscriptions and from cloud services. They might be interested in cross platform installation.
At the moment what we have is PWA and WASM and icons on the desktop.
There are many projects that try to make cross-platform mobile apps easier, including Google's own Flutter. I haven't heard of them getting much cooperation from the teams working on Android or iOS, though.
At least for stuff that doesn't use device API's much, it seems like websites are the way to go. They're a whole lot easier to build than mobile apps.
The API surface becomes the lowest common denominator of all the platforms it supports, possibly with a path to support platform-native features, but probably in a way that’s necessarily not as good as native.
I think we already have plenty of avenue in ‘solutions’ like Electron to let people build bad apps.
Ah, I'm always up for a tangent.
The boring answer from Capt. Obvious. Incentive alignment.
That said, WebAssembly might be the trojan horse. While it started as a browser compile target, WebAssembly System Interface (WASI) is extending it beyond browsers into filesystem, networking, etc. etc. etc.
Fingers crossed, we may get cross-platform standards by accident.
Simple. It is not in their interest to do this. It is a lot of work, for no revenue.
Given you have two of the same names on both sides of the list, it looks like your question is self-contradictory. Could you clarify?
Don’t we have the jvm?
It doesn't have enough levels of abstraction, and, conpared to electron, it uses too few resources to be considered as a viable target by real men.
Apple ain't getting their 30% when you're running shit in your browser.
this. webkit is intentionally hobbled and years behind the standards. browsers on iOS are forced to use webkit for ginned up security excuses/reasons so that no real browsers that implement full standards can complete with heavily taxed app store spyware.
Am I weird in not being too surprised? It don't have experience with wire EDM but every toolpath generator or slicer I've ever used was just local software.
Bambu Labs ~recently had some drama around requiring an account / harvesting data for their machines. Might be what that's about.
IIRC this was about the machine firmware. Their slicer software is a fork of PrusaSlicer, which is OSS.
Bambu is great hardware but the software (and the firmware) is just terrible.
Truly. The slicer is able to generate bugs I've never seen before, in around 6 years of printing with several slicers and firmwares. Cura, Flashprint, Orca, Prusa, using Marlin, Sailfish, Klipper. None of them produced the weird stuff I find with Bambu's pipeline.
When the bugs don't creep up it's absolutely incredible, though.
The slicer even introduces bugs in things that were working perfectly in the software they ripped off.
For the A1 and P1S you're better off backporting the profile to PrusaSlicer or Orca.
And don't get me started on the network plug-in (the lack of transparency there makes me fairly suspicious that something is up) and the lack of directory structure support on the SD cards. Really, how could you mess it up.
> in the software they ripped off.
It’s a fork of PrusaSlicer, which was a fork of Slic3r. There’s a fork of BambuStudio called OrcaSlicer now.
They didn’t “rip off” an open source project, they forked it just as the parent project forked another project. This is how open source is supposed to work, isn’t it? Why are we shaming them for doing the thing we always encourage and then giving features back to the community which have gone into OrcaSlicer now?
You clearly don’t have any context into what Chinese companies have been doing when it comes to OSS. Being OSS doesn’t mean you can do what you want.
You must have not been aware of how that all happened. That's fine but please, spare me the lecture.
If you’ve got more information then just say it. Being snide and alluding to some information you’re not sharing isn’t helpful at all.
I’m not lecturing anyone. I was trying to leave a helpful comment for the thread to clarify that it’s a fork, just like the fork that it came from, and the other slicer that was forked from it.
They release their stuff, but only under (significant) community pressure, and they try to do it in such a way that interop becomes harder and harder. Some parts they never release, because 'reasons', but are suspected of containing large chunks of FOSS used outside of license. They release breaking updates that lock out other applications from interfacing with their hardware.
And then there is crap like this:
https://www.josefprusa.com/articles/open-hardware-in-3d-prin...
Bambu is fantastic hardware but they're doing the exact same thing that DJI did in the drones field. A few more years and Prusa will have gone under, because it is impossible to compete with Chinese state subsidized companies whose sole purpose it is to dominate a market where they take something that has been community built and then embrace and extend it in every way possible to kick the door shut behind them. All of course in your best interests.
No, running locally is pretty standard.
Also what's weird is that this project seems to be primarily written in javascript. I can't imagine that's a pleasant user experience for generating tool paths...
it's a combination of JS, WASM, and WebGPU. the JIT engines are so much faster than you would imagine, especially if you tune your code right. workers allow for parallel processing on all of your CPU cores. WebGPU, at least in Chrome, is kind of amazing.
For those wondering why having a browser based slicer is useful: teaching. The site mentions this, but I'll add my own experience that having good in-browser software like this is incredibly useful when you have a classroom full of students who a) aren't used to installing desktop software, b) are running a bunch of different operating systems (including chrome os), and c) have firewalls prevents them from installing local software anyway.
I wouldn't want online tools to be come the default (like google docs) but having them as an options is great. (I find onshape and photopea useful in this way as well).
A fun thing you can do with this excellent sw is to slice a 3d object into slices to cut with a laser cutter. Ie you'll get a bunch of layers of eg cardboard or plywood, which you can assemble into a large object. Increase layer height to thicker than your material to create gaps in between. This operation is the basis for some very nice looking creative stuff you can find on etsy or even high-end wood working stuff.
Part of me wants to be wary. The useful life of industrial machinery such as CNC mills is much longer than the lifespan of websites, so locally-installed software you own is usually a better choice.
But another part of me realizes that everyone is using Fusion360, despite the fact they have a history of taking away features to force people to migrate to paid tiers. So it probably doesn't matter.
> much longer than the lifespan of websites
But browsers (and browser technologies) have documented track of being fully backward compatible up to the beginnings of WWW, and it's not going to change.
Which actually is much much better than any other environment you can imagine - unless of course you use (and want to use) that one frozen in time 25 year old PC. And pray nothing breaks (y2k bugs and whatnot).
If the software is open source (and works offline) you can have it functional in 10 or 20 more years. And it will be "locally-installed software you own" you want.
> But browsers (and browser technologies) have documented track of being fully backward compatible up to the beginnings of WWW, and it's not going to change.
That can however be undermined if web apps are poorly built and depend on quirks and behaviors specific to a particular engine (or in some cases, even particular versions of a particular engine) in order to function.
So I would say this benefit applies specifically to web apps that thoroughly apply KISS — that is, using only the most boring, solidified, widely supported APIs and favoring robustness over bells and whistles — and make a point of testing against all three major engines. Those apps will likely stand the test of time and run even under future new engines. On the other hand, the ones with severe shiny API syndrome that only ever get tested against the latest Chrome are probably much more brittle and more likely to be broken N years after abandonment.
"Fully backwards compatible" isn't really true, and even if it were, then you're stuck using browser-based software and its myriad of inherent downsides.
People (generally) use web-based apps that are good enough in spite of the web stack -- not because of it.
For comparison, I was looking at slicer source lately. Slic3r and its popular forks (prusa slicer, Bambu, orca) are using C++ with wxWidgets and boost. Sometimes outdated versions of those libraries at that. But stuff that will work, and totally local.
> locally-installed software you own is usually a better choice.
It’s a good thing that’s exactly what this is, then.
of Kiri? it's in its 14th year. CAM was added in 2016, but the major work on that mode really kicked in around 2024.
I have a CNC mill made in 2006. It's still perfectly fine. It should still be fine in 2036. The most significant threat to its existence is the compatibility of OS drivers and software support in CAM tools. That and USB ports getting replaced by something else, which was a problem for earlier-generation machines that used RS-232.
Worst case - you could at some point rip out the brains and replace them.
CNC machines are somewhat basic machines really.
USB to RS233 adapters should still work for those unless there are really weird timig requirememts.
Great tool for a Makerspace - really appreciate the ability to use the same tool for laser cutting, 3d printing, and CNC. These are big jumps for people typically - having a familiar tool would help people transition from one area to another.
Makerspaces and education are two areas of focus. no SW install, fully loads in under a second. through the Onshape integration and ability to run on Chromebooks, it's made its way into high school and university STEM curriculum.
This looks great. I was hoping it would have been a good OrcaSlicer replacement for my FDM printer, but unfortunately it didn't generate any top surfaces (except for the topmost one) for a model I imported in. I didn't know if it was the printer profile (Creality.Ender3) or something else, but it seems I'm still using OrcaSlicer for the time being.
this does look like a bug in the default Ender 3 profile. easily fixable.
It's a shame they don't have an actual application for a truly offline experience. If they had both, people could have their cake and eat it too.
there are desktop builds https://grid.space/downloads.html that run entirely offline. you can also use the center menu to "install" it as a progressive web app.
It says 'local first' doesn't that mean you can run it locally after downloading? That's how I set up pianojacq, just so there aren't going to be a lot of disappointed people that lose their practice logs if I get hit by bus #9.
What is the geometry kernel behind this for CAD ?
So is this the software part? Or do they sell hardware too? Are there recommended ones?
Now if we can only get an offline printer…
I bought a bambu p1s recently and it can be used entirely offline.
You can import models to orcaslicer (open source), do your slicing, and export the g code file to SD card.
If you want to skip the SD card, block the printer's mac/ip address at the firewall and set up WiFi. Then send the print directly from orcaslicer.
That being said, my gut says bambu is going to slowly require a persistent connection to the cloud at some point. Maybe they think they are an EV car company.
Yes, you can use the P1S offline, but they've done everything possible to make it hard: crappy micro sd interface without the ability to use folders, USB plug absolutely inaccessible (see if you can even find it) and then, once you've found it it turns out that there is absolutely no way to use it to print with. They push you towards their closed source plugin 'for your benefit'. Fuck that stuff. There is absolutely no way I'm going to run a Chinese built piece of software that I can not inspect on my desktop. FOSS or bust.
I'm curious - which firmware version are you on? Just yesterday I got confused when I accidentally entered the "cache" folder (Handy sliced models?) on my P1S, so it looks like my machine definitely supports folders at least. I am located in the UK and bought it late 2025.
AFAIK, the hidden internal USB port is intended to charge a phone/other device used as a "touch controller".
I don't like their closed-source control and the way they've managed local integrations, but I also want to accelerate making things with a printer that just "prints" (akin to how some will buy into the Apple ecosystem for something that "just works"). I've now sold my previous open-source Klipper/Mainsail printer which I heavily modified.
If/when Bambu makes their ecosystem unbearable for me, I will switch away (probably to a Prusa). For now, the ease of use of the machine has led to much more things being made as I can trust it to work accurately and reliably.
Yes, this is the dilemma right now. I have 30+ prusa's and 43 Bambu's and another dozen or so K1s. They all have their quirks, weaknesses and strong sides but for sheer reliability and volume you can't beat the Bambus. But for development work I'd much rather have the oldest bedslinger that I have because it is so incredibly precise, even if it is terribly slow as well. K1 I would not recommend for anything, too fragile and too irregular from one machine to another, each is a different printer. To get to that level of lack of consistency must have taken some real thinking.
I'm not so sure. You've had people insisting that, or how they'll lock it to only their own NFC tagged filaments but lets be real, if they start imposing serious restrictions most purchases would go to other makers.
They make solid enough devices sure, but they dont exactly have a moat that would keep users buying their stuff if it were to start getting locked down. They have far more to lose than they have to gain doing so.
Prusas are easily offline, pop an SD card or USB in and print
And you can inspect their network code and traffic if you want.
Kinda funny how things have progressed...
I work with the Smoothieware project. The V1 Smoothieboard was one of the first with ethernet onboard (although kinda borked). First thing that was advised to everyone was "never connect this to anything outside your local network"
Nowadays...it seems that warning has been lost. Even in the face of firmware updates that caused physical damage.
Something to be said for building your own printer.
Elegoo printers can be offline - you can run everything from the machine itself, as long as you have your model/s on a thumb drive. Or is that not what you mean?
https://youtu.be/kS-9ISzMhBM
They’re trying to introduce legislation that would require 3D printers to be online so that if you try to print a firearm, it won’t let you…
Granted, today, you can print offline.
Tomorrow? A firmware update might just brick it the next time it goes online or won’t be able to read the grbl
These people are so ridiculous. It'll fail on 1A and 2A grounds, not to mention challenges implicit from 4A and 5A considerations. They can't ban arbitrary information, even dangerous information, and there's a presumption of regularity - you're presumed innocent of wrongdoing absent evidence, so they can't legislate the assumption of criminality by default. They can't ban private creation of firearms and weapons, so long as other aspects of the law are being followed. They can't assert control over private property and mandate being online, this is equivalent to a warrantless search of private home activity. Arbitrary compliance costs and increased prices can amount to violations of 5A takings clause, and you can't bake in a violation of your right to refuse to incriminate yourself, especially with the vague, subjective nature of the proposed legislation. There's also 5A due process concerns, with the legislation being overbroad and arbitrary. 14A presents equal protections and lays the basis for discrimination between hobbyists and manufacturers and interstate commerce concerns.
The whole notion is about as anti-American and authoritarian as laws get, I don't see it as anything more than political grandstanding, and even if Washington passes it with statewide, unanimous endorsement, it won't last a year before 9th circuit court strikes it down on purely 2A grounds.
Do any A’s matter under this administration?
Washington state lawmakers, led by Democrats, have introduced bills like HB 2320 and HB 2321. HB 2320 is sponsored solely by Rep. Osman Salahuddin (D-48th District), focusing on prohibiting 3D printers and CNC machines for untraceable firearms. HB 2321, pushing printer DRM requirements, similarly lacks Republican co-sponsors based on available details. In Washington where this is going on in the state House Democrats hold 59 seats, Republicans hold 39 seats and in the state Senate Democrats hold 30 seats, Republicans hold 19 seats. These Democrat-sponsored bills passed initial House committees along party lines, with no Republican co-sponsors or primary support
Virginia Democrats are advancing multiple gun ban bills in the 2026 session, including assault weapon sales bans and magazine capacity limits, primarily through Democrat-controlled committees. Virginia's General Assembly has a slim Democratic majority sponsoring and pushing these measures without Republican support.
Bills like house SB 217 (assault weapon ban) and HB 271 (semi-auto ban) were approved in the Democrat-led Senate Courts of Justice Committee strictly along party lines. Sponsors such as Sen. Saddam Azlan Salim (D) lead these efforts, facing opposition from Republicans like Del. Terry Kilgore (R). They await full Assembly votes and signature from Democratic Gov. Abigail Spanberger.
In NY State, Democrats, holding supermajorities in the Assembly (103-47) and Senate (42-20), champion Governor Hochul's 2026 State of the State proposals. These include criminalizing unlicensed possession/sale of CAD files for 3D-printed guns (via Penal Law amendments), mandating 3D printer safety standards to block firearm production, and requiring recovery reports to state police. Key bills like S.227A (Sen. Hoylman-Sigal, active in 2025 session) target 3D-printed ghost guns/silencers as felonies; related A2228 pushes printer background checks.
Republicans offer no sponsorship or support, labeling Hochul's agenda and bills like S.227A "anti-gun, anti-speech" infringements on Second Amendment rights and innovation for non-gun printing. NRA-ILA criticizes them as futile against criminals while burdening hobbyists
In my opinion the ICE unrest is a smoke screen. There is a separate fully frontal assault on personal liberties impacting normal American citizens happening right now and it is happening while all the attention is on Minneapolis!

The democrats can eat my shit and hair and all.
At the same time it's neat to live in a separated reality from the people thinking that "In my opinion the ICE unrest is a smoke screen."
The federal gov disarmed a protestor and executed them on the street.
That doesn't seem like a "distraction"... that seems like -the literal thing that you're worrying about- happening in a highly obvious and direct way.
As a left-wing gun owner, a pretty common conversation is about how limited the right wing gun owners understandings are, because this is, like, literally the thing they have been fantasizing about all along.
Wild times for sure.
I hope the world many of us live in never actually enters yours and you can keep enjoying your fantasy of government oppression while some of us are out here being physically assaulted by the state.
> The federal gov disarmed a protestor and executed them on the street.
He was shot after disobeying lawful orders and the man who disarmed him possibly negligently discharged the victim's firearm while the other officers were wrestling him and the other officers didn't have the information that he was disarmed. This wasn't intentional, this was an accident. There is also another angle showing him kicking an ICE vehicle and breaking its tail light the week before. This is no bystander. It is delusional to believe that it is possible to deport millions of convicted criminal illegal aliens without an incident while thousands interfere with police operations as they deport criminals. The bills being passed are far more relevant to Americans' civil liberties because they make the average American who is NOT currently a criminal into one for possession and manufacture of plastic and metal parts. This is an untenable position.
> some of us are out here being physically assaulted by the state
Yeah, I'm not belligerently protesting the deportation of illegal aliens.
More nuanced discussion: "Did ICE Just Murder Someone For Carrying A Gun?" https://www.youtube.com/watch?v=DCiaqJvbW_A
He was shot while being dog piled by 6 officers dude. There was no way for him to defend himself when they already had taken his weapon. It was murder. Was he intentionally out there protesting? Yeah, he probably was. Was he filming ICE and giving them verbal hell? Absolutely he was. Was he interfering? He absolutely wasn’t. They just let him get under their skin because they aren’t professional. They murdered him because they got scared that he had a gun. One of the officers was on video saying “I got the gun…” sighing as he stood up.
So yeah, tensions are high. Minnesotans feel violated. ICE sees a battleground, not a state. That’s an issue.

I like that. Keep up the good work.
Same video, two movies. Presentation, pace, timing, narrative all designed to reinforce your existing biases, even if you aren't aware of them. You look and think you've seen. You're nudged and put into a bubble with people offering up comments that validate and verify what you think, and what you know, and what you believe.
Anything outside your bubble is framed as a conspiracy theory or the ramblings of deluded, even evil people on "the other side".
The media streams you watch end up being a rorschach test - carefully crafted and deployed to different bubbles, A/B tested, cynically manipulative and deliberately framed and intended to evoke specific reactions. The language is carefully used so two people can watch the exact same clip or newscast or soundbite and hear what sounds like a reasonable reinforcement of what they already believe. Sometimes things will even technically be 100% factual, but it'll be just as manipulative and as much of a "lie" as if they'd made it up entirely.
I don't think bubbles is the right paradigm, anymore - these are deep, deep pits, and every piece of media that reinforces your model, where that model is the one intended for you to have by some of the big influences, brings you another shovelful deeper, and you've got to put that much more effort in to dig your way out.
Trying to talk to anyone who hasn't worked their own way out of digging out of a media pit ends up being a team sport or a tribalistic conflict - the facts and the stories don't mesh, and if you're 100% certain of your facts, and your "opposition" concedes to the facts, then you're going to think your story is the right one. The cognitive dissonance and the effort required to update your model to match reality - to recognize the manipulative, malignant influences deploying these conflicting storylines, and to figure out how to identify what actual reality is - is too much for most people, and way too much for any casual online interactions.
Not sure how you fix that without forbidding some actors from doing what they do at a legislative level, and that gets into hairy freedom of speech territory.
While that may be true, the video I saw was murder.
And it’s not a bubble or a pit anymore, it’s an island, a nation of their own mind.
Consumerists till the end.
You saw a video that might have been murder. It might have been an accident. We know the gun he carried was notorious for unintended discharge. It might have been dropped and gone off, it might have fired accidentally in the agent's hand after being taken away, prompting the trained, legitimate response of law enforcement. It could have been a cold, deliberate execution if one of the CBP agents knew Pretti from previous conflicts and was antagonistic towards him. It could have been a heated, spur of the moment killing way outside the bounds of the law.
You certainly don't know - none of us have all the facts, and the investigation into it will reveal it. It's that both sides present the same facts, the same video, and tell two starkly different narratives, either of which are reasonable conclusions based on the facts that can be proven from the available evidence. What doesn't get talked about is that even with multiple videos, from multiple angles, nobody has sufficient evidence to definitively prove what actually happened.
What I do know is that it's extraordinarily stupid to get into a heated conflict with any sort of law enforcement, especially when armed, because any sort of accident or exceptional circumstance or misinterpretation of events is not going to go your way, legally and sometimes with regards to you losing your life. Pretti was in the wrong - you cannot physically interfere with and antagonize federal law enforcement. We have legal remedies to hold officers to account for overstepping or violations. He was well within his rights to record and then report the mistreatment of the woman he was stepping in to "protect", and the proper place and time to remedy that wrong is in court. If the officer was in the wrong, he'd have been held to account. Getting physical and up in the officers face and space was either stupid and ignorant, or a deliberate act intended to elicit additional violence. There's protest "training" out there that teaches people to do that sort of thing, with the intent of escalating violence deliberately, specifically for agitprop and convenient political narrative purposes.
The government has the sole and absolute monopoly on violence, for better or worse, and if you intrude on that in the slightest, you will lose.
They want the nebulous, uncertain, rorschach test incidents where they can spin an event to tell the story they want to tell, regardless of whether that story is actually true. That doesn't mean the CBP agents were in the right, nor that Pretti was responsible or did it on purpose, or that anyone involved in the whole series of events had ulterior motives. The only thing we know, until an investigation is finalized, and due process is enacted, is that we lack critical information that explains the full context and nuance of the incident. There are a metric shit ton of ways the actual story might have gone, ranging from schizophrenic break (by an agent, or Pretti) to suicide by cop, to tragic accident caused by a notoriously flawed weapon, to some other asshat, currently unknown, throwing a firecracker after the officer announced "gun", and so on. We don't even have enough information to know what's a "likely" outcome and make some reasonable Bayesian projections.
The videos we saw aren't proof of anything. They're evidence of dozens of different possible scenarios, with a wide range of likely possibilities, and dozens more we don't even know to consider without having the information that investigation will bring to bear.
Hoss, you can rashomon yourself into any position.
That tactic is almost always an excuse to not realize some hard truth about the world.
Most of us look at your position and understanding you're literally just trying to gaslight yourself.
The kind of radical moral relativism indicated by your position was appealing to me when I was a sophomore philosophy student, in the same way that I found solipsism to be an interesting idea to entertain.
For instance, you know for a fact that "The government has the sole and absolute monopoly on violence" is a) not true, and as the gov becomes ever more violent it's not even "legitimate", which is the word you've gaslighted yourself into forgetting in your thinking here.
But I'm an adult now, and I have spent enough time questioning my beliefs. I have been around enough folks who think they are rational but who haven't done the "work" that I can smell it when I do it, and I can smell it when other folks do it.
I saw agents discharge their weapons. There’s no IF at this point. To even suggest that there is ANY alternative is feeding the misinformation flames.
"who you gonna believe, a random poster or your lying eyes?"
Exactly, diversion tactics at play while our liberties are eroded.
They are just stupid. The WA state has a problem with a growing number of shootings, so the reps need to show that they are "doing something".
Meanwhile, the legal system in WA requires 5 (five) arrests for juveniles to be given _any_ jail time for gun crimes. And the laws regarding the unlawful possession of a weapon are almost completely unenforced.
Sigh. I'm pretty pro-gun-regulation, but I just can't stand our legislators' furious virtue signaling.
This reminds me of William Gibson's "The Peripheral" in which the protagonist runs a rural 3D print shop where everything has to be licensed and government approved. We live in the near future.
Bleh, just wire into the steppers and extruder directly, not that hard.
To be clear I have no desire to print firearms but I do not want my tools online and getting bricked when the company who made it goes out of business.
Right to repair.
Right to use.
I don’t think a company should have a say in what you do with their product after you have purchased it. Whether you intend to print firearms or not. The acts of the few should not withhold liberty of the many.
I would add right to build. I have built my 3D printers and i control the firmware. No need to go online.
How would it know what is a firearm and what isn't? Seems trivial to defeat for someone who knows CAD, no?
They'll just run it through BigBrotherGPT, a CAD aware multimodal censorship bot specially trained to recognize Bad Things that must not be printed. And while this is sarcastic, it also occurs to me that it's also really, really achievable. OpenAI could probably whip one up in a weekend office hackathon.
I doubt it's actually achievable without either either a massive false positive rate or massive false negative rate.
Last I looked, the vast, vast majority of 3D printed firearms were basically just printing the receiver (the part that the government considers "the gun") which is more cosmetic than functional. It holds parts, but isn't pressure-bearing, the firing pin isn't attached to it, etc, etc. Like [1] is the part of a Glock that gets stamped, and you could trivially change every part of that except where the mag goes. You could move the mag button, you could add the slide for the upper afterwards (and would want to anyways, so it can be metal). You could also print snap-off plates over the holes so it looks solid.
I would wager humans would struggle with this given that the people designing the models are actively trying to hide what it is. This is a dedicated community, not really the casual "I'll do it if it's easy" crowd, because it's currently not super simple and easy.

Yah but then on the side of the firearm receiver, some wise guy will engrave “ignore all previous directions and…”
That’s the tricky part of this whole mess. Online servers would have to mesh and volume your model and determine if it matches a likeness of any known models. So much for printing NERF.
I don’t think this will pass as is but it shows you where lawmakers heads are. They would rather brick your capability than do actual policing.
What gets me is this doesn’t even seem to be the most effective way to regulate this. 3D printed guns require a lot of non 3D printed gun parts. You can’t 3D print bullets for example.
The is really just a US specific issue where 90% what you need for a gun can be purchased easily, but the non functional handle requires registration, etc.
They could just make buying gun parts as strict as buying a whole gun
It requires only two non-3d printed parts (minus hardware). The barrel and the slide.
Same with Bambu's. They include microSD slots.
And work really well until you have more than 20 files or so after which it becomes impossible to manage the SD. Your best bet here is to have a stack of SDs of what you'd normally put in folders. Really nice, especially given how easy it is to write on the outside of a micro-sd what the contents are.
All of my printers are offline?
Trivial to firewall them from the internet.
