[Me...] Posted June 3, 2019 Share Posted June 3, 2019 Hi all, Today, while trying to qualify a new .4mm stylus in Z- on an 8mm sphere, had the tip try to go through the sphere during the second scan of the ball. I'm using a Duramax with an XXT TL1 head (non articulating). I've never seen this happen before. Qualifying a new stylus is programming 101. I set the proper radius for the probe, I tried reducing the sensitivity, the probing dynamic, switched the .4mm to a different stylus plate, tried a different .4mm probe and when I tried to continue where I left off on the qualification, the probe actually moved into a position to try and take a scan from under the sphere... I'm a bit flummoxed here, spent over an hour to try and qualify 1 probe. Anyone else had this issue or have any suggestions? Link to comment Share on other sites More sharing options...
[Ow...] Posted June 3, 2019 Share Posted June 3, 2019 Have you re-referenced the reference sphere lately? The reason why I ask is it sounds like the the system may think the reference sphere is in a different position? Other than that, I can't think of anything that would cause that but, I haven't used anything smaller than a .8mm probe on a Duramax either.

[Me...] Posted June 4, 2019 Author Share Posted June 4, 2019 Valid question, however, I always reference the sphere when I'm qualifying a probe. Link to comment Share on other sites More sharing options...
[To...] Posted June 4, 2019 Share Posted June 4, 2019 Double-check to see if correct reference sphere is active. I'm guessing your 8mm is Ref Sphere #2. What do you mean by "I set the proper radius for the probe." Link to comment Share on other sites More sharing options...
[Me...] Posted June 4, 2019 Author Share Posted June 4, 2019 My 8mm sphere on that machine actually has 2 references (2 and 3). 3 is the default, I did try both though. (This was set before I started working at this company so I don't know the reason behind it.) Originally, prior to trying to qualify the probe, the radius defaulted to a 1mm for some reason. I set it to .0079 inches after the first time the probe crashed into the sphere. My concern is with the pathing of the probe on the sphere. It takes the allotted hits on top, then scans the first helical scan with no issues. Toward the end of the second scan, the probe gets to the back side of the ball then "jumps" in X+ before trying to move below the sphere. I'm starting to think about calling a priest in to exorcise the machine... Link to comment Share on other sites More sharing options...
[Da...] Posted June 4, 2019 Share Posted June 4, 2019 Jason, where is vector pointing to? (under stylus system management) Link to comment Share on other sites More sharing options...
[To...] Posted June 4, 2019 Share Posted June 4, 2019 Jason, I have experienced this problem before when the calibration sphere radius was incorrectly input in the Reference Sphere Management. Link to comment Share on other sites More sharing options...
[Me...] Posted June 4, 2019 Author Share Posted June 4, 2019 I use this same sphere to qualify .4mm probes in X-/X+. It has worked fine for both manual qualification and the qualification program for that star probe. This is the first time I have seen an issue with the sphere, but it is also the first time on this machine I have tried to qualify in Z- on that sphere. As an update, this morning I was easily able to qualify the same probe on a newer Duramax using conventional qualifying techniques on an 8mm sphere. I will check on the vector...
