      We run leadshine closed loop stepper motors off external drivers connected to the duet through the expansion breakout board.

      We keep seeing a little step at the end of every movement that looks like the motor didn't quite get to to where it wanted to go. Generally motors run smoothly from origin to destination, but this is smooth up until about 1.5 mm from the final spot after which the stepper motor "jumps" like its performing a cleanup step to get to where it needs to go.

      I am not sure the cause, or how to better describe it. Anyone have experience with this?
