Hi @bar,
I have done another calibration cycle and now it looks better.
I still have some questions about the correct calibration routine and hope you help me.
I have a detachable anchor that is mounted on the floor. On the floor lies a thick spoil board with 30mm height and on top the actual work piece which is 15mm multiplex.
Do I have to run the calibration on the floor or is it good to run it on the spoil board and if it is run on the spoil board do I have to set its thickness to 0?
Whats the perfect angle for the belts in the following sketch?
Thats my current anchor.
