Hi Thanks for your reply, I have not even got that far as to even start the Plasma Cutter.

I am trying to configure an output on an external 24v relay to trigger the plasma torch in place of the trigger switch. I am unable to configure the "system" to create a circuit for the relay.

Additionally when i try to set the THC enable functions in UCCNC where i input the torch up and down pins, then press enter to apply the settings, they always return to 0 and no settings are applied.

The Plasma Cutter is a Unimig Razor 45 which is CNC capable with the pin outs for the torch fire, arc success and a divider circuit for a THC.
