I am once again pleading for your help. I am trying to setup a disc probe for some projects coming up and have never had this issue occur so I am scratching my head at a solution. Perhaps everyone on here can shine some light on a solution.
Below is a picture of the probe build as well as utility editor. As you can see, my Calibration Mode settings are ghosted out and unable to be edited for some reason. This is the same thing that occurs on each of my Scan Module head style probe builds, but on anything with the Touch Probe force module that is unlocked again. That being said, I am unsure if the issue is caused by anything that can be changed within that dialog box. This is the first company I have worked with that uses a scan module, I have only ever used touch trigger and need to brush up on the scan procedures etc. to fully utilize.
The issue; When calibrating in any head orientation besides A0B0 the disc takes the initial hit on the sphere, and then beings taking the touch probe hits along the equator. At this point it will try and swing the entire diameter of the sphere, coming to the bottom where the shank is located and it will crash and alarm out. I am going out on a limb and assuming the Cal-sphere to disc probe size relation could be the issue as the sphere only .59025" and the only disc we had laying around was an 18mmx7.5mm.
I can get this to successfully calibrate in A0B0 with good results, and it looks like it follows the -5°/5° start/end angles automatically but when it got to A90B90 the disc is still trying to swing around to the bottom of the Cal-sphere. In A0B0 it takes the initial hit atop the sphere, takes hits along the equator in clockwise/counterclockwise rotation and then beings a scan in the same manner, at 3 different levels, counter and clockwise once again.
I opened a case and the tech sent me this article;
How do I calibrate a disk stylus on an analog probe? Am I not seeing something within that article that should be of help or was that just them tossing me a piece of paper and telling me to figure it out? I have read other forum links and wanted to just calibrate in manual mode as that seems to be the easy way to solve this, but as you can see that isn't even an option I can toggle.
Avg Insp - maybe have a gander at this:
https://docs.hexagonmi.com/pcdmis/2019.1/en/helpcenter/mergedProjects/cmm/probes/disk_stylus_calibration_notes_and_procedure.htm It's 2019, but it helped me get thru a jaspered-up disc dilemma. I think
constadin is on the right track. I was having issues with non-A0-B0 disc fun, but it helped to read the instructions closely. (not being a wise-guy, but.... the hexatechs wrote this canned disc stuff! - so read it several times ) If you'd like? I can send you the params that worked for me. The 5 HITS - 2 LEVELS are definitely in the disc cal recipe.
MAN + DCC is too.......
NB... good point of the size conflict
Is this an analogue module? I am not so familiar with the hardware side of things, but for scanning head setups like the one OP is having, 2 levels with 5 hits should be the go to way as explained in the documentation
oh ok, I did not understand that the whole measure menu is greyed out. First time I see this... Is this the case with any other probe? Have you tried redefining the probe under a new name / probe file?
Yea it does the same thing to all of my probes that utilize the SM25 style head, on the one touch probe in my rack it allows alteration of parameters. I think PCDMIS has an auto scan setting that cannot be altered within a dialog box inside a program but can be inside the settings editor.
I tested this yesterday with the settings editor open but lost admin rights as the IT guy isn't able to unlock it for me permanently yet. I am waiting on elevation of IT approval for admin rights before I test it more later on.
I changed the start and end angle of the hits along the equator and it looked like it took hits on same spots before I changed it, so maybe I altered the wrong parameter lol

You are right in your assumption - 1.0'' will sort this out. We have both size spheres onsite. I did try on 1.0'' and it works with analogue probe/scan module:
Ø18 disc should clash on .59025" (Ø15mm) sphere as per trigonometry calculation (in millimeters):
