    Default cut motor won't stop and runs spuratic

    Hey everyone just was doing some projects and have developed a problem with my machine. the cut motor will not shut off when it is supposed to. And it run sporatic. I did a search for the problem and it came up with replace brushes. So I did that and also did the motor speed sensor. But really no change.
    Changing the brushes didn't make sense since the motor won't shut off.
    I call LHR last week and was told an engineer would email be solutions. But no luck there easy.
    So I come here for expert advice and input
    Thanks in advance for help

    Check the x termination board under the machine. You may find a burned resistor, melted trace, or broken capacitor connection.

    As posted above, the C1 Capacitor is sometimes the cause of this problem.

    I would order a new X Termination Board.

    Lets hope you have not bypassed the right side cover switch. If the switch is bypassed then while you are changing the bit, the cut motor could come on.

    Usually after a shock like thumping on the top of the machine and the C1 hits then opens.

    Favorite Saying.... "It's ALL About the Brass Roller"..... And "Use MASKING TAPE" for board skipping in the X or breaking bits.
