Got everything wired up in my Hypertherm 1250 according to the diagram in the Candcnc manual for the 1250 model. I am still learning to use the mach interface but I am not able to fire the torch manually from the software. The DTHC online is lit green on the screen but pressing the manual fire doesnt work. What am I missing? I do hear a click coming from inside the 1250 case but get nothing else.
