First four pictures: beam line status at beginning of shift - Beam aligned to MID

Idea is to check M2 parasitic motions again on M3 popin. therefore bringing M2 close to 0 with all vertical motors and Tx as much as possible without using beam on the popin.

Adjusting M1 pitch with it

Approch - drive roll and correct rz offest to stay in at the same horizontal position - adjust also ROLL Offset to show 0 in middle position

When ROLL IS DONE continuE with rx and then ty

offset calibration needs iteration. We started the second iteration but could not finish.
