    Hello
    My issue is my slow down motor does not show up when starting up the press.
    The motor spins freely and all connections look fine.
    I have a damaged SAK board.
    Not sure if the two are connected.
    Any help diagnosing the problem would be appreciated.

    Hello
    Follow the motor cable and check if the plug has connected probably. Also check if there is any damages on the cable.

    Cables are clean. I s2apped with another and still having same effect.
    I also swapped HAK boards and it doesn't follow the board.

    I think that you have a flat cable connexion if not you must verify your variant key
