Hi All

Was wondering if there was any script that i could add to a button to toggle negative homing on my Z axis on and off?

Reason being i home my machine at the top of the Z (furtherest away from bed) but when useing plasma i have a floating head so i need to set my Z to negative homing, its not to much of a hassle to go to options -> Homing and toggle it, but thought it would be cleaner to have a button (flating head active) with an LED..

I am pretty new to Mach and its scripts so any help would be great, thanks all!!
