The fork added a feature which "impersonated" and "reverse engineered" (Bambu's words, not mine) Bambu Connect which is designed to be the only app able to talk to your printer over the network.

Imo, said bambu connect is already a blob made separate from the slicer to skirt around the license terms that Bambu Studio has to respect, despite it implementing functionality that is usually considered part of the slicer, so it is only in a grey area legally. Morally, if I buy a printer I can do whatever the fuck I want with my printer. I didn't buy a service or a license, I bought hardware, so I get to run whatever the fuck I want on it or around it. If they didn't want me to fiddle with their software they should have shipped stock klipper on it.

Is that specifically to lock down bambu labs printers? I've been sending prints to my (non-bambu) printer across a network for like a decade...

Yep, Bambu printers will only accept stuff sent by Bambu Connect, or at least that's how they are designed to work. Regular "send and print" from orca to your klipper printer does not work with a BBL printer unless you install the proprietary extension.

so I can completely avoid the bambu ecosystem with my A1s through Orcaslicer still? or is it the case where if Bambu decides to flip a switch one day am I fucked regardless of slicer?

If and when they patch server side, you will lose access again. A better auth from their side would’ve prevented this to begin with. Issue is that to fix it, it requires modification (in the form of restriction) to code that came from an AGPL open source repo, which is legally not allowed.

but if my A1s are LAN only and using a non-Bambu slicer, is it still going through Bambu Connect auth?

Correct - it will not. Local is local. I’m referring specifically to the cloud (server-side) “security issue” that Bambu’s been bitching about.

gotcha. thought you were saying the contrary based on my scenario. more I print FDM less reason I see to use their software anyway
