Could the encoder be loose on the motor shaft? If it was moving relative to the motor, the servo system would rotate the motor to compensate.
Hi. The Z motor (dc servo) does not hold the position while cutting.
I noticed on a belt that the motor is retracting during operation and as a result, the axis is raised a few mm in the end.
?

ok. i will check. (there are a lot of vibratons) . It is symptomatic that the Z axis always creeps UP.
Spindle cable is separated ....
I grounded the "servo control casing", but not the machine ...

Solved !
the encoder was slipping in the motor shaft. ccc
