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.
I have an autocalibrate routine on my bridge cmm and I probably should have one for the optiv.
I see where you do the camera to the ring and then one probe to the ring.
Am I to assume then that this is a master probe?
I have the tesa rack so there's only two probes, but should I be doing both to the ring or not?
My current routine is: Camera to ring, moved yes / Probe 1 to ring, moved no / Probe 2 to ring, moved no.
Then Probe 1 to sphere, moved yes / Probe 2 to sphere, moved no.
"The Master Probe is normally the first probe calibrated after a machine Certification (Calibration) and only matters if you need to use it in relation to other probes on a single part."
I found this somewhere else in the forum. I have heard the term "Master Probe" before but didn't know exactly what it meant.
Disregard my comment about saying "Yes" to the sphere move every time you change Probes.
I honestly have never used multiple TTPs in a routine, but this was before I had a tool changer so that may change. I have always used multiple TIPS within my probe builds because I am limited to star probes on my machine but never multiple separate touch probe builds. I always have 1 Vision Probe and 1 Touch Probe used in my routines.
Since the relation of one TTP to another TTP is not important to me I always choose that the sphere has "Yes" moved because I do not need it to be related to another touch probe within my routines.
That being said, that is GREAT to know for the future. So if the relation between each Touch Probe build you use in a routine is important for you, I believe you could just choose which one is the Master Touch Probe and relate your others to that.
