Testing the MST-109 microstep stepper motor driver at high rpm (3000rpm)
A short video of testing the microstep driver for stepper motors MST-109 with the 86BYGH250AH14J stepper motor. The supply voltage of the MST-109 driver was 31VDC, and the current setting resistor was 2k7, which corresponds to a current of 4.5A. The maximum speed of the stepper motor in the video is 3000rpm. Control software is mikroCNC. Link for stepper motor drive MST-109:
