Only one z probe before M3
I'm new here!!! First I want to apologize for my bad English!
I built a CNC plasma cutter. The machine is controlled with Ramps 1.4 and repetier firmware. Everything is fine. Now I want to control the z-axis in such a way that after the M3 S255 command (switch plasma relay on) the Z-axis first moves to the z-max limit switch and then back to a certain height. Only then is ignited. Is this possible?
