mach 3

on my mach 3 control screen you can adjust your voltage. I am stuck on 120 volts if I'm running a g code or not. I shut everything off and back on still stuck. I usually restart the program and it fixes its self but this time it just is stuck on 120 when I try to increase it goes to 121 and goes back to 120 I click down, and it goes 119 then jumps back to 120. ldr motion systems table . 2016

If it's a candcnc control, you're not communicating with the hub. Try unplugging the hub power for a few seconds. That usually does it for me.
