I've seen these edge locators with an inside corner and a hole centered over the intersection of the sides of the corner. I don't know how to make one of these fixtures accurately. A good one is probably somewhat expensive.
Steve Stallings had a $120 touch probe made by Wildhorse Innovations (I think he paid $140 but they have reduced the price.) It is modeled after the patented Renishaw probe that recently expired. It has a steel ball machined on the end of the probe rod. I figured I could find a ruby ball with a drilled hole somewhere relatively cheap and make it even better. Anyway, Mach is set up with some routines for probing edges and the center of holes, and this has apparently been done to some extent in EMC, also. There seems to be a hole finding routine in nc_progs. The center of a hole needs no information about the probe, just that it is centered to the spindle and the ball is spherical. To pick up an edge of a part directly (without the above-mentioned corner fixture) the routine needs to know the diameter of the probe ball. And, then, it would be most convenient if it could do the same thing the touch-off button does in Axis, for both X and Y. This would be really convenient, as I always fumble with whether I should enter +radius or -radius for the touch-off value. I have to always do G1 F10 X0 Y0 after touching off to catch when I have done it wrong.
