Isn't Voron/Soval more open?

Voron isn't a company, nor are they after a profit, all designs are 100% opensource. Sovol runs on a profit and uses opensource designs to run their products.

I'm aware but I don't see how that changes those devices being the most open 3D printers.

I'm still rocking my Ender 3 Pro, I printed a part 13 hrs straight and it came out fine not saying it can't be better eg. faster, multi-color/material but yeah works for me right now with Cura

I upgraded from the 3 to the 5, and had some great experiences with it. My Ender 3 was such a Printer of Theseus; I think I'd replaced everything except the extruded aluminium frame by the time I upgraded. But that's part of the hobby, surely? Like, just having a printer and having it print things first time, and never taking it apart or replacing chunks of it to see if that would work better, seems kinda dull to me…

Surprisingly for me I have only replaced the magnetic mat and the hot end - mat was magnetized the wrong way so I had to cut it with a razor but yeah

I'm bad though, I have the nozzle run into the bed as there is noticeable sag/difference at the middle of the bed, but it's good enough for me there is some elephants foot going on but not crazy

> You must put authorization on your server if you don't want others connecting to it. Unfortunately, the CFAA doesn't necessarily require that authorization is implemented through technical means, and it definitely doesn't require any authorization to be technically robust.

The point is that they distributed AGPL licensed software which legally speaking puts them on very thin ice if they say "actually you're not allowed to modify that software we gave you and explicitly told you you could modify to do whatever you want." This is a direct quote from the Affero GPL: > When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent…

You're certainly allowed to modify the software, but that doesn't necessarily give you the right to connect it to hardware owned by other people. And AGPL does not provide for any right to services -- only a right to use and modify the covered work.

For example, AGPL doesn't prevent you from being banned from a Mastodon server.

The key part of the sentence you quoted is "... to the extent such circumvention is effected by exercising rights under this License with respect to the covered work" -- meaning, you can't use anti-circumvention to prevent people from using or modifying the copyrighted code.

Prusa is still the most 'open source-ish' choice, but they're no longer a polar opposite to Bambu, in 2023 they started making efforts to stop commercialization of their designs, stopped sharing source/design material for their PCBs, etc. Then in 2025 they changed their 'open community license' to say users may not: “Sell complete machines or remixes based on these files, unless you have a separate agreement…” and “T…

So you want European companies to keep being nice and "open", do all the research and invent new technologies and products for the chinese to copy and sell cheap clones of!

There's nothing secret in these 3d printers. The Chinese are very capable of reverse engineering these products and out innovating these companies.

I am an outsider on the details of the Bambu software requiring users to go through their servers in China and the closing of their software. Still I suspect it is about spying in wartime, Bambu printers are at the core of the Ukrainian war effort, the main reason even Ukraine is winning since januari 2026. First China prevented Ukraine from using any of the drones that they sold in millions to Russia while exercisin…

Personally while I don't think what Bambu's doing is great, it's not like there aren't a dozen manufacturers that can generally match their printers at similar pricepoints, and don't have these issues

It's what the chinese have been saying for decades. More to make themselves feel better than anything else, yet Europe, Japan, or the US are constantly fighting with their infinite spies, and even though they are more than capable to 'outclass' everyone as you say, for whatever reason they never do. Even local Japanese strawberry farms are having issues with chinese spies for decades now (source: widely known, and personal experience).

They don't out-innovate anyone, they copy and use infinite slave labour to flood the market with cheap inferior products. Pretending otherwise is disingenuous.

The Chinese can be oppressive, thieves, and innovative.

This is false. After the authorization-related firmware changes last year LAN mode doesn't allow 3rd party slicers to connect. LAN mode is also abandonware with numerous issues and missing features that they've had no interest in fixing. Orca slicer has had to rely on hacky workarounds in Bambu's buggy networking plugin just to be able to connect to printers in a different subnet. https://github.com/bambulab/BambuStu…

I can connect to my P2S in LAN mode with OrcaSlicer just fine (currently using the latest 2.4.0 nightly). > be able to connect to printers in a different subnet This is a separate issue, I think even Bambu Studio can't connect to printers in LAN mode on a different subnet.

> This is a separate issue, I think even Bambu Studio can't connect to printers in LAN mode on a different subnet.

Yes, that's the point. The nerworking is broken. The issue isn't unique to a specific slicer, their software sucks. Orca ran into the issue because they wanted to make a basic feature that works on every other printer on the market work on a bambu.

That is literally what they said: > I can no longer use OrcaSlicer to interact with my printers (e.g. sync filaments) and start prints remotely. The remote interaction with the printer goes via their cloud. > If you tell me my new toaster can send a live video of my bagel to my phone then I am entitled to receive that functionality without being subject to your shitware. No you aren't. You might be able to use 3rd pa…

Well I guess we'll have to agree to disagree because we have a fundamental difference in our view here. If they advertised the printer as having certain functionality that relied on their cloud and if the printer was also advertised as working (with full functionality) with third party clients then they don't have the right to later try to block people from using those cloud services. A SaaS company enjoys full contr…

> if the printer was also advertised as working (with full functionality) with third party clients

I don't think this was ever the case. But I'm happy to be proven wrong here.

You hook it up to the network to use monitoring features like a remote camera view to make sure your print is going smoothly. SD cards work but it's extremely less convenient than just printing straight from the slicer. You can use any slicer you want but Bambu wants only their slicer to directly connect. CLI slicing is not something you want in general. Visual confirmation of the toolpaths is very important to makin…

Only on LAN mode, which disables remote monitoring.
