Are those tts holders? I found that with my 770, no matter how good i indicated the probe, it would change every time i took it out of the spindle. This was also true for the run out with the tools. The tts don't have a way to keep the holders lined up the same way in the spindle like the bt30s and cat 40s. What i did was scribe a line on the side of the spindle, holders, and probe. Then i lined up the make every time i loaded a tool or probe. Doing this helped the repeatability, helped hold .002 true position on holes, and .0005 on profiles.

the probe isnt necessarily to blame for the 2nd op misalignment. you need to probe a machined feature not the rough stock. mill a hole all the way through your part and use that to probe off for the 2nd op.

Ok I will give that a try on the next part thank you. I have another part to do on Sunday morning. Also have a setting ring on the way.
