Yes, its a builtin EMC function that I have used before. Someone here had posted a link to an oak tree engineered surface probe you can make from a slot opto and some of the telescoping brass tubing you can get at the model/hobby shops, so I made one for about a $10 bill, and used it to map the surface contours of the floor plate on Bertha as I was considering replacing that 3 oz of steel with an oz of alu. I got that piece done, but have since gotten side tracked, still trying to figure out a foolproof way to register the front and back, and machine the spring groove for the cartridge follower. Its a very shallow, high angle dovetail in the steel version & I've not stumbled over a suitable mill (yet). See G38.2 in the emc manual. Concise but adequate description, but ATM I still need to get my new drive box wired for a probe input.
