Z axis servo has been getting hot sitting at idle
A servo motor should never be hot at idle. Tell us more on your z axis configuration. Is it direct drive or pulley reduction. What is the motor continuous torque rating? Z axis weight. Type of leadscrew and pitch.
Gecko servo drive will always dither a bit when idle. Tuning can minimize but if there excessive force on the motor due to z axis weight, it will be difficult to fine tune it.
