I have a creality falcon 5w that im converting to a plasma cutter cnc using a bestarc cut55xp (non hf) but its not starting the arc when i start it up, it only traces the gcode but doesnt cut. I have IN from relay going to the pwm wire and vcc to dc+ and gnd to dc-. The trigger on the torch works and starts the arc. Any help is appreciated!
