Hi Leo,

Can you provide more details?
How did you invert the pulse?
What are the voltages at the inputs of the DRV8824?
How far did the motor move in one direction and how far back did it move?

the voltages at the inputs of the DRV8824 is 12V.
Drive the motor, corotation the 100 pulse and then reverse running 100 pulse, One period deviate is about 8mm.

Start with 500 positive pulses, 500 reversals, 1 second between positive and negative, 12v working voltage。
the pulse cycle from 500us to 1ms. we tried both of them. After 20 repetitions, the distance is more than 1mm.
