Morning Fellas,
I have a calibration issue I'm hoping someone can help me with. The company I work for has an old Sheffield Discovery III in an automated cell. Fixed on the granite is a 3/4" cal. sphere that has been in the same spot for years. SP25M probe with a star stylus. Now, the star, best I can tell, is a Renishaw A-5000-7629 except the Z- tip that fixes the assembly to the stylus holder has been replaced with the center of a star body and apparently the probe file has at some point been modified somehow to reflect this change, essentially leaving me with a 4 tip star that spans 18mm's center to center.
My problem is the hard drive died on the PC and was replaced and PCDMIS was re-installed and as many files as could be scrounged up were, and were placed in the appropriate directories as best we can tell but apparently something was lost because now I am being forced to do a full calibration of this star. Best I can tell there is some sort of predetermined scan sequence that is performed during this full calibrationof the probe.
Since the span of the star and the diameter of the cal sphere are almost identical the Y+ tip is crashing into the sphere during the scan sequence of the X+ tip. I feel a simple modification of the start and end angles would resolve this BUT they are grayed out.
Is there any way to "unlock" the start and end angles so they can be modified or a way to do a standard point calibration without the scan sequence. I feel there has to be some way because apparently at some point in the past the "full" calibration was performed because up until the disc died I was able to do partial calibrations which will allow adjustment of the start and end angles.
I hope this makes some sort of sense to someone that might have the answer I seek...
Thanks-in Advance
P.S.-- the probe interface is a Renishaw PI200 and the head is a PH6M, if that info is needed...
