// digitalWrite(stepPin, HIGH); //pulse the motor high then low 400 times to achieve one spin // delay(15); // digitalWrite(stepPin, LOW); // delay(15);
I finally got everything to work. However, my stepper needs more torque, I think, because it doesn't like to spin up. If I use my finger to get the platform spinning, the stepper will engage and keep it spinning.
Here is what I use:Nema 17 (unknown model - if you know how I could Identify it, that would help with current limiting)A4988 driver
