Wayne, I have never seen any work done with Artcam for a lathe, but had to Ask. I know very little of it, but have friend that is sharp, use to be a seller. I have a macro that I made with the help of others that will read posotion at time of tool change, go to tool change posotion as set in settings page, ask if you want to auto touch off tool and then goes back to where it was and starts running.
