I tried several times on an Raspi 5 (ubuntu) with two different cameras the tool but i always get the tuple error when the button toggleCrosshair is pressed or when the calibration is started. When i start calibration after safe controlpoint the printer fetch the head an go back to camera at this moment the tuple error occurs.
the full print is :
CRITICAL : Camera failed to retrieve data.
CRITICAL : 'tuple' object does not support item assignment
CRITICAL : Critical camera error. Please restart TAMV.
Hopefully anyone has an idea where the bug is.
If i set a break point where these print functions are located it does not halt.
Best Regards Thomas
