When you are ready with the torch, push the F5 key on your keyboard. If you have the "Torch On" (ports and pins) input configured to sense the arc has transferred to the plate and you are in plasma mode with THC ON selected, Mach will start motion, else hit the "CYCLE START" button after the torch fired. A point worth mentioning here is that it is propably better to use the "RUN FROM HERE" function as the Mach3 innerds loose some steps when you "PAUSE". You might find your part aint the size it should be. ;)

Run from here does not work well with a floating head that requires a G28.1 then a G92 to set TOM.  Set next line is rock dependable with plasma and a floating head.

IF mach looses position when it is paused then run from here will not help AS you had to pause in order to use the RFH so unless you rehome it will still be off.

In over 5 years of using mach I have never seen it loose position using feedhold (wait for it to stop) then stop.
