    Weird moves on the lathe ( please help solve this) (see pictures)

    I will try to explain the best I can but this is really weird.

    I can only move 1 axis at a time no matter how I connect both stepper drivers.

    See pictures

    -----------------------------------------------------------------------------------------------------------

    Normal connection

    Z+ and Z minus are working as they should
    No move on the X axis

    -------------------------------------------------------------------------------------------------------------

    If I switch signal cable ( X signal on Z stepper driver and Z signal on X stepper driver)

    No move on the Z axis
    X axis become Z axis

    --------------------------------------------------------------------------------------------------------------

    If I switch power cable going to stepper motor (signal cable in normal position x signal to X stepper driver --Z signal to Z axis driver)

    Z axis become X axis
    No move on the X axis


    ------------------------------------------------------------------------------------------------------------------

    If I switch both, signal cable and power cable (from X to Z and Z to X)
    X axis move
    No move on the Z axis

    Seems X axis stepper driver has problem.
