I offloaded IP, BFY and MNY by moving stepper motors and picomotor after vacuum evacuation.
IP and MNY can be offloaded but BFY cannot be offloaded because F0Y stepper motor somehow stopped working at the position around -7000 steps.
We are not sure what happened but limit switches of F0Y stepper motor say it doesn't reach the limit, so it is not likely the stack of stepper motor.
For further investigation, it is better to check the resistance of F0Y stepper motor.
Note:
Of course, it is not good situation but not critical issue because we can change the BFY setpoint instead of BFY offload.
After that, we also need to offload MNY again but BF picomotor seems working well, so we can do that.
