This is my first reply on this message board, and I am glad I found it. My experience with run out is the CMM does a good job of telling you True Position the the center, but good luck getting an indicator to agree with the CMM. I have trouble getting people to understand the difference in the way the 2 devices work. Concentricity does work very well for this but make sure you understand how your software reads the measurement. I am running Tutors for Windows on a B&S machine. The software reads twice the actual and I was giving false information without knowing it until I got some good info.
Good luck, hope you have better luck than I did.
