servo PID tuning

Hi
I have the same problems trying to tune my INTERMAC machine(i believe that BIESSE&INTERMAC are the same group).My motor are BRY200 and BRU500.I have the same slow rotation until i enable(F2) the linux cnc then it stop the rotation.In other motors i experience the same problems with you.After the advise of Todd Zuercher i will try to check for interference or maybe miss tune servos

Slow movement of a servo is expected if the drive is enabled but the closed-loop controller is not active.

The answer is to have the drive enabled by the controller.

And disabled when the controller isn't. (The disabled part is the most important part.)
