I was thinking about using the two beams that are transversally cut by the well because that way I can measure the length of a circular portion and have an exact measure of the radius independently of the home distance or the part diameter being known. The only thing that would matter with this approach would be to know exact distance between one beam and the other and they off course must be perfectly perpendicular to the wheel axis of movement. And obviously Leonardo, make a youtube video and tell us about it when > its working. :) Be sure I'll let you guys know as soon as I do something. In fact, I can't wait to see and show you the mazak turning with LCNC. After that, I hope I can start converting the grinder as soon as poosible!
