    xpro V3 Ox built CNC: A-Axis won’t work.


    i have a question regarding my CNC xpro V3 I am using with my OX-like built CNC router. It was running fine, until I have tried to change the stepper settings to a finer setting by moving the jumpers and Pot adjustment, because the Z-axis acted a bit sluggish.

    After the adjustment the A-axis, which is the designated slave axis to the Y-axis does not move at all anymore.

    The things I have tried:

    Changing GRBL settings,

    uploaded my initial GRBL settings again,

    Used different G-code senders,

    tried switching the stepper motors to check if it’s a motor problem.

    None of the above worked.

    Now I have measured the resistance between to connector pins at the board at the a-axis driver.

    There is no resistance between the A1, A2, B2, B1 connectors when the power is off, means , it seems like they have connection throughout.

    I guess the board is malfunctioning ?

    Any help appreciated.
