Don't break the calibration chain!
I am posting this in hopes to have it made into a sticky since I see this issue arise a lot in the Vision section. This document perfectly explains the calibration process for calibrating offset with a Vision primary system with TTP.
Here is my Auto Cal program for vision to tactile. The move points I have in there are to make it as automated as possible and are based on the coordinates of the machine. At the beginning I have to have the machine navigate around the sphere, so I make sure it doesn't get hit. Parameter sets are created in the probe utilities, under measure.

Does this autocalibrate routine fully automate the process or does the vision-to-ring step still require three manual hits to locate the ring? I have tried this same routine and it always requires the locating hits if I choose Yes to has moved, even if I choose DCC in the Parameter Set. It would be ideal to get the full process automated. If the artifacts are places roughly in the same place each time it doesn't seem all that necessary to find it with manual hits don't you think?
