I was running a part that has had a old program on it on a global s 9.15.9 chrome. I found it oot. I was told that part has to be ran on the 7.10.7 global advantage. So I did and found it to be good. Same part same program same head and porbes. Why would this part run good on 1 machine and not on the other? I can run other parts to within a couple tenths of each other on both machines but not this one.
Do both machines have the same probe body? (TP200, TP20, hp-s-x1h, etc)
It might have something to do with fast probe mode. The analog scanning heads (hp-s-x1h) can use more force than a normal TTP like the TP20 or TP200.
You could try turning on fast probe mode at the top of the program and run it again on both machines.
Also just a heads up, fast probe mode is supposedly less accurate (I have never done a study so IDK)
When you say "same probes"...do you mean same probe builds on each machine however different probes and modules on each machine or you are taking the physical probe off one machine and running it on the other?
I'd start by breaking down each potential cause for the delta.
-Ensure method of measure PRG routines are absolutely identical including temp compensation settings, in-routine touch and force parameters.
-Ensure fixturing is identical and holding part without rocking or inducing some skew or bias that your routine isn't adjusting for.
-Ensure physical components are in good working order, tight and calibrated. (cal sphere, probe styli, extensions, etc)
-Ensure probes are "balanced" if they are analog scanning, and all probe touch/force parameters are identical
-Conduct a lower level matrix on each machine to affirm it's calibrated correctly.
If nothing surfaces to rectify the deltas, after checking off each one of these... You have to start to suspect one of your machines might need to be serviced, calibrated or volume mapped.
How much of a difference are you seeing in the measurements? Is it one of those times where a feature measures right on the edge of the tolerance on one machine and barely out of tolerance on the other machine? The type of difference that could be explained with random measuring error. Or is it a bigger difference than that?
