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
