  • Asteriks on Tip Names

    Can anyone tell me why some of these tip names are preceded with an asterisk (*)?
    Sometimes they are duplicates, mostly unused.
    Thanks.

    *= Haven't been calibrated. Need to be calibrated before use.
    It will stick if you throw it hard enough.

      they have not been calibrated since probes have been reset, never trust just because there inst an asterisk there doesn't mean its a recent or legit calibration .

        I appreciate the responses, that is what I thought it meant. just seems odd some of the entries are duplicates of probes that are calibrated...

          dont know why you would have a duplicate ? there may be a minus sign (-) in front of one of them. (A90B90) (A90B-90)

            No, they are duplicates. the stylus was just calibrated on Monday, if they were active they should have calibrated. We had a similar problem situation with an "L" shaped probe that would try and calibrate non-existing impossible (for our cal. sphere) angles. I deleted the asterisk tips, none of which were the impossible angles, and it has behaved ever since.
            This particular stylus in the photo above has developed a nasty habit of crashing PC-DMIS when called from the rack unless preceded with a timer...sometimes. I looked at the probe and saw those asterisk tips same as the other stylus, I've since deleted them and crossed my fingers hoping to resolve the software crashes.
            Just curious if anybody else had a similar experience.

              If you are using a "L" shaped probe or star probe they may not be duplicates but the angles for the other tips available for the probe build.

              for example the tips shown above are "T1A0B0", if you have an "L" shaped probe then there should be "T2A0B0" as well.

              With that said I'm not sure why there would be duplicates in the above picture

                That makes sense but that stylus one only has one tip:

                  One thing that can corrupt probe files is using special characters in the naming convention. When naming probes, features, dimensions, etc. in PC-DMIS, only use letters, numbers, and underscores.

                  Not sure if that will fix your issue, but it can lead to odd problems

                    I agree, but there is a huge body of work here using the existing styli. I spend a lot of time throwing patches on existing programs, their last programmer was pretty good with metrology but not so much with programming. We added a second programmer to keep up, there are 4 B&S machines here and one Zeiss. I try to focus on the Zeiss because the other guy is really good with DMIS but he is on vacation.
