i was going off the setting of the YOC335 Peak 3.5a and RMS 1.8a so i thought the peak would be the same.
i have had a look and there are no identifying information on the motors but in the info i received with the machine it say they are two phase 57/3 stepper motor. i presume that stands for series 57 and 3amp but the only info i can find says the revs are 600 for this motor, you might know better ?
now switch seven makes sense
