Looking at adding a floating head to my new build, I've found some code that goes in sheetcam to be run before a cut, this lifts the head, drops it and zeros the DRO etc, what I can't find is where the signal from the floating head micro switch is fed into the mach3 system??

Is it just another limit switch? Or does it need a seperate input signal?

cant find any information on this bit.

i guess a limit will do it as it will only close when the torch has hit metal, but wouldn't that trigger an e-stop??
