[Ma...] Posted Tuesday at 06:23 PM Share Posted Tuesday at 06:23 PM I would describe myself as a fairly novice Calypso user, so please forgive me if I'm making any obvious or silly errors. I'm working on creating a program for an angled part. The part is bent at 145 degrees and has features on both sides. To measure the part, I'm trying to set up 4 new styli, each one normal to a surface of my angled part. The four styli all use the same stylus system, and they are as follows: A=35, B=90 A=145, B=90 A=215, B=90 A=325, B=90 The stylus system which the 4 above styli use has other orientations (-Z, -X, +X, -Y, +Y) which I have used before and regularly requalify with no issue. However, when I try to qualify these 4 new orientations for the first time, they all invariably crash on the reference sphere. I have tried reducing speed and reducing sphere coverage, but they will always crash near the end of the qualification program. Oddly, they don't seem to actually crash on any part of the reference sphere. They seem to qualify normally - they don't hit the stem of the sphere - and then Calypso will just tell me that they crashed, so I'm unsure what's going on. I don't have this issue when trying to qualify a stylus which is parallel to the machine's coordinate system - only styli at angles. Does anyone have any advice? Thank you so much!

[Ma...] Posted Tuesday at 06:29 PM Share Posted Tuesday at 06:29 PM Manual calibration or program for calibration? What type of head? Link to comment Share on other sites More sharing options...
[Ma...] Posted Tuesday at 06:33 PM Author Share Posted Tuesday at 06:33 PM I believe I am using a qualification program. Does Calypso generate a program for qualification when a new stylus is created? When attempting to qualify these (and all other styli), Calypso instructs me to probe in the direction of the stylus shaft, and then the machine traces spirals around the qualification sphere. I have never created a program for calibration/qualification myself. The head on the four styli I'm trying to qualify is a 1.5mm sphere. Link to comment Share on other sites More sharing options...
[Ma...] Posted Tuesday at 06:56 PM Share Posted Tuesday at 06:56 PM Calypso is not generating probe calibration program, but for that you have to have created a probe with correct shaft vector. Are you using both joysticks to achieve correct vector ( probing in direction of stylus shaft ) ? Link to comment Share on other sites More sharing options...
[Ma...] Posted Tuesday at 07:25 PM Author Share Posted Tuesday at 07:25 PM I'm not sure about both joysticks as my control pendant has one stick for Z movement and one stick for XY movement. I do try to use the XY stick to impact the reference sphere dead-on with the angled probe, yes; it's a bit difficult to be precise with that movement though given the angle.

[Ma...] Posted Tuesday at 07:33 PM Share Posted Tuesday at 07:33 PM OK i forgot that one joystick is for Z and rotation 🙂 Do you calibration fail on manual calibration? What type of calibration do you perform? Link to comment Share on other sites More sharing options...
[Cl...] Posted Tuesday at 08:02 PM Share Posted Tuesday at 08:02 PM If you use multiple ref spheres. Make sure the correct one has been chosen (made that mistake myself a few times). Link to comment Share on other sites More sharing options...
[Ma...] Posted Tuesday at 08:04 PM Author Share Posted Tuesday at 08:04 PM (edited) I'm not actually sure what type of calibration I'm performing. In the attached image, I click the "Qualify stylus" button, circled in red. Doing so prompts calypso to tell me to probe the reference sphere in the direction of the stylus shaft. When I do, it touches off a few times and then begins tracing a spiral pattern on the sphere. This was the only way I have been trained to calibrate a probe. Is there another way? I'm sorry I can't be more helpful Edited Tuesday at 08:11 PM wrong image uploaded Link to comment Share on other sites More sharing options...
[Ma...] Posted Tuesday at 08:30 PM Author Share Posted Tuesday at 08:30 PM All, Thank you both for your help and suggestions. I believe I've solved the issue! Looks like I wasn't being quite accurate enough in initially probing the sphere. Taking a bit more care to perfectly line up contact with the sphere dead-on seems to have resolved my issue. Thanks again! Link to comment Share on other sites More sharing options...
[Cl...] Posted Tuesday at 08:31 PM Share Posted Tuesday at 08:31 PM I would increase the sphere coverage to 180° Link to comment Share on other sites More sharing options...
[Ky...] Posted Tuesday at 09:10 PM Share Posted Tuesday at 09:10 PM Please sign in to view this quote. Though I agree on principle, technically it doesn't matter for an XXT. It is always 180. That option only works with active heads. As far Marina is concerned, did you ever get a message about confirming the angle when you were doing it manually? So long as you don't measure too far off, that can buy you a bit of breathing room when qualifying at the more difficult angles. Link to comment Share on other sites More sharing options...
[Ri...] Posted Wednesday at 11:31 AM Share Posted Wednesday at 11:31 AM (edited) Please sign in to view this quote. Don't go for dead on, be off center enough so the program will probe a few points, and a dialog box will pop up waiting for the user to enter the articulation angles. Typically, I try to be 10 or more degrees off center. I have always found this to be the easiest method, after automatic qualification will work great.
