external Stepperdriver direction phenomenom



  • Hello, I have the following problem:
    I have two motors on the x-axis , as soon as the printer moves in the positive direction both motors run synchronously.
    But in the negative direction the motors run to different directions. It's the complete opposite of how they should work.
    Why does this happen and why do they not run synchronously in both directions?

    So one of the motors always runs in the same direction? It sounds like its driver is not getting the direction signal.
