How can you be sure your microswitches behave the same way when actuated fast or slow ?
To ascertain it is the stepper/driver, do fast identical forward/ backward mvt, slow forward/ backward, a mix ..... Mark the shaft, the moving part, measure with a caliper whatever ...to see if you come back at the same spot.
