I currently am using a floating z-axis for my torch reference. I would like to add an engraver in the near future. This would be much simpler if i could clean up the z-axis by removing the floating portion. My question is this. Can i solder a lead onto the shield of the torch(powermax 45) and attach the other to the working piece thus when the torch shield touches the work it connects the leads and the makes the reference?

Thanks
