Hi there,
I already checked some threads, but I still don’t get the camera of my laser module working correctly. Snapmaker and Luban up to date. I did the calibration but I don’t get any useful camera picture. The colors of the tiles change, but thats all. Any hints?
Not sure if this is the same issue I was having back in December, but here is the response that fixed my issues:
Downgrade the Luban to 4.0.3.
Downgrade the firmware to 1.13.2
After downgrading Luban and Firmware, the camera functioned perfectly. I can’t believe they haven’t fixed this issue with the latest patches though. I’m afraid to update my software because I use my laser a lot.
Hope this helps.
thanks Gralli 
Unfortunately Luban 4.0.3 isn’t working, at least with MacOS 12.4
