Re: [CAD_CAM_EDM_DRO]stepper is very hot

Shabbir,

Steppers do run hot!

If you have the current set correctly (usually a potentiometer, dip
switch, or resistor on bipolar drives; and the power "dropping"
resistors on unipolar drives) then the heat is normal. There should
be less heat when the motors are running compared to when they are
stopped (idling).

Hope this helps.
