Re: [CAD_CAM_EDM_DRO] Stepper NG??

Hi Jon,

If it's a bipolar motor, you should have two pairs of windings, they
should not be connected! Very high resistance to case? It SHOULD be
high! Possibly in excess of 1M. At any rate, quite high. Do you have
the specs for the motor? What you DON'T want to see is SHORTED motor
winds, either to each other, or CASE!
