One of the differences between the two modules is the maximum output range. The NI 9401 (max 5.25V), 9402 (max 3.4V). Do you know if the motor requires higher than 3.4V to operate correctly? Have you been able to perform microstepping?

In the series connected configuration of the motor, the specs call for 2.3 volts, so I should be ok there. As for microstepping, no, I have not done any.
