Re: [CAD_CAM_EDM_DRO] .9 deg/step motor

It sounds like you have a coil wired wrong,or maybe your maximum speed and
acceleration may be too high. Maybe starting off too fast. testing steppers
i usually set them real low till i know the motor is wired right and turns
without skipping or going back and forth into lockup. cul brian f.
