Comment on Stepper not moving

  probably, unless you’ve managed to get a bad connection or something- just something to look at when you’re opening it up to get to the pot. try and see if you can check the voltage specs on the new part, compare it to where its at. It’ll save you a lot of grief if you know where it should be before hunting around for it.

    Afaik steppers don’t care about voltage. It’s about current since it’s all inductors inducing magnetic fields.

      Nearly all stepper drivers deliver a constant current to the motor. While the nominal voltage needed for a stepper is essentially “irrelevant”, setting the correct voltage determines the current available for the stepper, by the driver. Ohms law is only really applicable to a stepper motor when it is not moving.

      A minimum voltage is still required to overcome back-EMF.

      Without going into the maths, your voltage settings determines your available current, basically.
