    CNC Router spindle starts spinning after start up

    Hello
    I have a Chinese made cnc router, it has been working fine for quite some time but today as soon as i power on the machine, the spindle starts spinning by itself and spins at high speed and I cannot even stop it by pressing the ON/OFF button on the DSP.
    Have to switch off the machine to stop the machine.

    Any idea what could be wrong.

    Thank you.

    You need a breakout board that has Safety Charge Pump. Maybe this one will work for you:

    You may be able to install an external one:

    It is basically a watchdog that monitors the controller to confirm that the signals are valid.
