Can't get step motor to run

  • Hello,
    my problem is that i can't get my step motor (Nanotec ST4118S1404-A) with the M5STACK TOUGH to run. I have a STEPMOTOR-MODULE-WITH-MEGA328P-DRV8825 Module with three DRV8825 drivers. I'm trying to run the M5STACK example code from the Arduino library, whitch i modified so that i dont have to press any buttons to run the stepper. I hape someone can help me.
