"Measure Probe" window with locked options

[Hirxm]

So I have been wanting to qualify a disk probe but I haven't been able to do so because apparently I need to edit some fields on the Measure Probe window, but they happen to be grayed out! I don't know why this happens or how can I enable all those fields.

[AndersI]

What probe do you have?

[Hirxm]

It's a 2x55mm probe, using SM25-2 but it happens with every probe.

[AndersI]

I don't think the SM25 will let you do neither manual nor disk calibration - it's a scanning head and uses only scans during calibration.

[Hirxm]

Interesting, so what would I need instead SM25?

[AndersI]

A touch probe - TP20, TP200, Tesa (I guess those have a Hexagon name now, but I'm not that much into hardware), for example. But why use a disk? There are lots of threads in this forum about disks, and most of them ends in "don't use them"...

[Hirxm]

We run a program on a part that requires to measure through scanning a not so easily accesible circle. The disk works just fine in this case so that's why I need to qualify it.

[NinjaBadger]

As anders said the SP25 qualifies by scanning around and (crucially) over the sphere - which you can't do with a disc. There's an adapter called a TM25 which allows you to use TP20 modules on an SP25.

I disagree with the second part however. I measure a lot of seal grooves etc, and I couldn't do it without the disc probe. I get excellent results with them, but you do have to be careful during calibration.

As I said, I'm not that much into hardware, almost exclusively offline, so I only repeat what others say to me when it comes to actual measuring :-)
