    ok going to prepare, then move axis, move 1mm,
    Now if I pick x I move +oo8.0 when I rotate it back to zero I have no movement back.

    If I do the same thing to z it works moves and moves back.

    Do I have a bad cable????
    Or card.

    Well I flipped x for y and it's still in the X not the cables. Got to be a setting in the card or a bad rumba.

    Does the "Auto home" work? Have you done this before trying the move axis?

    Another thought - have you checked the end stop is in the correct position on the rumba?

    Found the problem! It was me.

    The End stop Switch was in the wrong place in the rumba it was X max not X min

    I found two wire reversed on one of my stepper motor cables, at the RUMBA connector end, black and green reversed, simple fix though.
