Bambu Lab pushes a “control system” for 3D printers, and boy, did it not go well

Security measure? Boxing out third-party tools? Or something more complex?

do tell? i just checked the Prusa blog and don't see anything that seems related. what happened?

There's an old blog post you can read here:
https://blog.prusa3d.com/the-state-of-open-source-in-3d-printing-in-2023_76659/

and an interview with Adafruit here:
https://blog.adafruit.com/2023/07/1...nging-face-of-open-source-hardware-companies/

A follow-up has been promised but nothing yet. Prusa has outright said that printers for desktop usage will always have an open source firmware+slicer and will be open to third parties, period. Their bootloader is closed source but they've said it's simply a bootloader and has no other functions. There are not full circuit schematics for the MK4/XL/Core One or some CAD components for the Nextruder released yet. I'll hear him out but if the firmware ever goes closed source I'm out.
