Subject: Compensation of M2 RY motor for the case of Piezo off 

We plan to put the piezos of M2 off, in the (unprobable) case that this is the reason of the "jumps" in SASE3 trajectory.

Therefore, I measured the change on RY and RZ motors, to correct all the positions

Fig 1: initial position, Motors Ry=10.5425 and RZ=-14.7200  Piezo Ry =5 and Rz=5

Fig 2: Ry is compensated, Motors Ry=10.4990 and RZ=-14.72  Piezo Ry =0 and Rz=5

Fig 3: Rz is compensated, Motors Ry=10.4990 and RZ=-14.7574  Piezo Ry =0 and Rz=0

 

Differential values: RY needs to be adjusted by -0.0435 and Rz by -0.0374
