After some revolutions of motor dr8v811 DRV getting too hot, it stops the motor like glitches. If you have a current probe, please look at the current waveforms to confirm proper current regulation.

In reply to pankaj chavan As a quick summary do let me suggest either slow decay or mixed decay, and try to use only as much current as really needed. This thread has been locked.

You can try lowering VREF, which should reduce the current. How does that relate the the timing of the PWM signal sent to the step pin?
