> I don't understand why any software other than their own should be entitled to use those resources

That's not a genuine argument, nobody "feels entitled" to anything. Bambu made a deliberate choice to architect the product this way, deliberately placed themselves in this gatekeeping position, and they're deliberately working towards removing any other form of access to our hardware.

Maybe I'm mistaken, but I don't think that's what is happening. They aren't doing anything to block OrcaSlicer or any fork from working with the printer using LAN-only mode. It's only if you want to use Bambu Lab's servers for essentially a remote-access solution (which, by the way, kind of defeats the privacy-oriented purpose of running some of these forks) that they're saying you should use their own software.

Thought experiment: the core of macOS (Darwin) is open source. Does that mean everyone running Darwin or a fork of it should be able to use iCloud services for free?

All this outrage essentially sounds like "since Bambu Lab's slicer is open-source, the open-source community should be able to point any slicer at Bambu Lab's servers to get free remote monitoring services". And I don't think that's right.

They did. Since the first update in early 2025 LAN-only mode isn't enough to use 3rd party software anymore. Eventually they (partially) caved to the extensive backlash and added "developer mode" which completely exposes your printer by removing existing access controls, coercing users into either giving up control, or giving up basic security in order to maintain full control of our printers.

It sounds like they're doing what people want. People seem to be ascribing a lot of mal-intent to actions that don't seem malicious to me.

> completely exposes your printer by removing existing access controls

If these printers are in LAN-only mode and you want to point 3rd-party software at them, don't you kind of expect the existing access controls (which are probably at least in part tied to cloud services) to be removed? Behind a LAN with developer mode on, you're generally going to (1) not be exposed to the internet anyway, and (2) probably know what you're doing and would be implementing access controls yourself anyway.

If you want a completely open (hardware and software) 3D printer, don't get a Bambu Lab machine I guess? A big part of the value of their printers is that they've managed to make everything so seamless. Some of that relies on a somewhat closed ecosystem. They're the Apple of 3D printers, but everyone keeps expecting them to be the Linux, just because their slicer (or parts of it anyway) is open-source. If openness is more important to you than those conveniences, go with a different brand. It's a good thing we have choices as consumers :)

No, and it's absurd that you would suggest that on a technical forum in 2026, and no, they're not tied to cloud services in any way. Do you also grant root access to anyone on your LAN, by default and without credentials?

My mistake, I didn't realize you were just here to engage in bad faith bullshit and peddle the company's PR statements from last year. These changes are happening after we already bought our printers.

I love my X1C. It's way ahead of any other 3D printer I've owned or built. I stuck it in a VLAN from day 1. Have had it in LAN-only mode for years. Works great. I haven't followed the company's PR statements, but seems a little strange that they would tell people not to get a Bambu Lab printer for any reason.

I'm sorry your experience has been so terrible or that you thought you were buying an open-ecosystem printer. I never got that impression, so I never expected it.

And in 2026, I wouldn't trust access controls on their own even if Bambu Lab did keep them enabled in this situation (who's to say they don't include a back door of their own?). I prefer security at the network level, enforcing access controls before any untrusted hosts can even see a machine that I want to protect on the network.

		We've strayed so far off topic. Try to get a handle on your fanboyism and you might be able to see this discussion more rationally. Why do you feel the need to justify your purchase in public and talk about how great the printer is? Bambu make good printers and nobody is disputing that. And for the record, my own experience hasn't been terrible at all, it's been predominantly positive. However that doesn't change the fact that their overall dishonest corporate behavior, pushing unjustified user-hostile changes after the sale, violating the AGPL license of Prusa slicer, and legally bullying independent developers is immoral, illegal, and generally indefensible. Nobody wants to live in a world where this sort of behavior is normalized. Furthermore "LAN only mode" has been neglected and generally half-broken for years. It was a hobbled alternative before they broke it even further. https://github.com/bambulab/BambuStudio/issues/4512 > I prefer security at the network level You do you, but the world has moved on since the 90s. Communication is expected to be end to end encrypted, credentials should be revocable, and you generally don't want to grant every process on your device unrestricted ability to set your house on fire. Disgracefully, this is being done in the name of "security".
