A floating z axis, so you're going to use the 3 ball arrangement to set the torch height. It does sound heaps easier than faffing about measuring the volts. This could be up and running PDQ.

Looking good. We'll need a movie when you get it cutting :D

Hi Robin

actualy no Im not going down that balls route, the idea is to put a limit switch on floating "Z" and use as a ref, bring "Z" down torch will touch metal and lift floating "Z" into ref switch, and stop then lift "Z" by a known amount (switch travel + clearance of tip) and fire, this way every start will be automaticly set to differing thicknesses of material, as the distance of lift will be a constant. well thats the plan, Mach3 has this ability
