Vision and Probe Calibration Offset

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.

Awesome, I was told by hex app engineer that a auto calibrate routine with vision as a primary and tactile as secondary was not possible. Thanks for sharing bfire85.
