I've got a situation where I need to find the center axis of a vertical rod with a digital probe. So kind of the opposite of finding the center of a hole. I need to do it many times and am realizing I could save a lot of time if I wrote a sub routine to do it. I'm no gcode expert but I can probably write some code to do what I want...eventually Before I do that though I thought might check on the boards here and see if someone had already written something like that or if maybe there is another solution I'm not considering. Thanks
