    Maybe earthing problem

    Hi all
    I need a quick fix,
    Problem is, when Mach 3 plasma is booted up my keyboard arrow signals with move the axis on screen ok,
    When I switch on the power inverter to power the stepper drivers the signals is still ok on the screen,
    But when I switch power on to the stepper drivers the screen is non responsive and sometimes I get message from the computer saying the USB being used has lost its ,

    I have changed to new keypad and new computer that we had spare for back up.
    Could this be a earth problem somewhere

    Thanks Guys

    Absolutely it could be. Time to start clamping things down a little, maybe?
