[Al...] Posted September 29 Share Posted September 29 Our CMM was serviced 2 days ago where the Tech replaced the RDS-CAA. I had replaces the XXT sensor a week ago but we kept having issues. My question is: is the probe not supposed to be at the sphere where it is currently scanning? 1 Link to comment Share on other sites More sharing options...

[No...] Posted September 30 Share Posted September 30 I still don't get what's suppsed to be wrong in that screenshot. Is it something in the dialog window (I can barely read it)? Link to comment Share on other sites More sharing options...

[No...] Posted September 30 Share Posted September 30 Oh, that's a stylus, not a match! 😁 Sorry, didn't notice that. 1 Link to comment Share on other sites More sharing options...

[Je...] Posted October 1 Share Posted October 1 (edited) Please sign in to view this username. , Thanks for asking about this. RDS-CAA replacements are common, and it's not uncommon for customers to troubleshoot issues by first replacing the XXT, especially when the root cause is not immediately apparent. Zeiss can analyze several problems remotely, and sometimes this can take the guesswork out of component swapping (not always). The spring inside the XXT tends to wear, so it's nice that now you have a fresh RDS and XXT going forward. First of all, you mentioned that you "never mess with the settings." Start messing with the settings. Caution and training have their place in the metrology lab, but your best way to learn and advance your skill is to dig into Calypso with curiosity. I'm not advising making mass changes without understanding the implications. However, I am daring you to see how far you can develop. And there are ways to experiment in Calypso while mitigating risk. When I'm learning new software, I keep a text file open to log the changes I make to settings. These forums, pressing "F1" (help files) in Calypso, and consulting Zeiss application specialists are all great ways to learn. To your immediate question: na_vor's response sounds likely. The orientation and/or reference sphere geometry that was specified when beginning qualification is probably different than the actual orientation on your cmm. Check to see which direction your reference sphere is facing, and make sure it lines up with what you choose for "Ref. Sphere Position". The graphic on the right side of this image can look confusing before you understand what it's communicating. That graphic is "Tilt" of the reference sphere. Pretend you're above the reference sphere looking down. Once you define the Tilt angle, the other remaining axis, perpendicular to the Tilt angle, is called Rotation. For example, 180° Tilt and 0° Rotation points straight upward. Keep us posted on what you find out. Edited October 1 2 Link to comment Share on other sites More sharing options...
[Al...] Posted October 1 Author Share Posted October 1 I have: Tilt 180 Rotation: 0 I reset the masterprobe & qualified again. It is still not finding the part when do the manual alignment! It just goes to a different location... like to the side or down 1 Link to comment Share on other sites More sharing options...
[Je...] Posted October 2 Share Posted October 2 Hi Please sign in to view this username. . You don't need to set the Tilt to 180° and Rotation to 0° for the reference sphere when qualifying stylii. That's just one option of many. The important thing when typing in the Tilt and Rotation is to make sure you're defining the reference sphere's orientation in the same way that the actual, physical reference sphere on your cmm is oriented. If you set the Tilt to 180° and Rotation to 0°, then make sure your reference sphere on the granite is pointed straight up (there's a bolt on the black reference sphere holder that loosens and allows you to reposition the sphere. Make sure to tighten it securely again if you move it). One possible root cause (shot in the dark) is that sometimes a stylus will get qualified but the operator accidentally probed a different stylus on the same stylus system. Calypso then qualifies the probe, but it thinks the stylus is in a different location than what the user thinks it is. If you'd like more help with this problem here on the forums, perhaps describe the problem a bit more or post some screenshots that show the problem. Also, the application specialists at Zeiss are terrific for helping troubleshoot problems like this. If your company has a ZeissCare License (annual software maintenance agreement + calibration), then you can contact Zeiss and have them remote-in to your computer free of charge. I'll send you a PM with my contact info. Feel free to reach out for more help, or keep posting here. Interested to hear how this turns out.

[Ri...] Posted October 2 Share Posted October 2 You can create a refence sphere for each of the 4 articulations shown (In the op's image)and one more for 180°. This is how I am setup, the use selects the required reference sphere. 1 Link to comment Share on other sites More sharing options...
