So I tried printing from an Orcaslicer appimage, and I get the following log:
The connection to the printer works, I can acess the device tab, see temps, turn on camera and so on, I am just unable to upload stuff. And the error seems generic.
The instance of the bridge is running directly from the python script in a python 3.12 container.
