You can laugh. I had my machine for 8 years and I cannot use the majority of my Renishaw commands.
I use CALL OO10 and PMOD=
To get the following:
Center of a hole, Center of a boss, Center of something in x-direction and center of something in y-direction.
I think My PMODs are 6, 9, 11, 12. These are all center points
I do have a program I wrote that self calibrates the probe crooked-ness and diameter. I put a ring gauge on the table and the program does the rest.
I also use my touch probe with the Renishaw and since the spring on the touch probe is weaker, I get accurate results using z-direction.
I use M21 to turn on the probe and manually touch the part followed by G92 to set "Z"
I need help in using PMOD for X, Y, and Z in "End Face" gauging.
