Calibration/qualification stylus SDO Error -1105

[[Da...]]

Hello i cannot fix it
Contura G2
It says "Incorrect number of points"
i have this error while calibration, some stylus going fine, some having problems with some positions
for example
My reference sphere is 20 mm
Stylus is D1,5_40
I do only a simple angles X+ X- Y+ Y- and A0 B0

The reference sphere is fully accesable for choosen angles, there is no colision with shaft.
i found this solution,
https://carl-zeiss-industrial-metrology ... -of-points
and i did reference position this two methods

the reference sphere angle is changed
from last fine qualification, is it may be the problem ?

___Edit
In sytlus system i deleted all problematic angles, set them again and it works 🙂

I've had this happen multiple times after our machine was calibrated. I believe some probes get corrupted. What I found to work is to delete the probe that's giving you the error (not the entire stylus system) You can't delete a probe no. that's active so you will need to switch to a different probe no. Next, recreate that probe and manually qualify it.

I had the same issue a few months ago immediately following a Zeiss calibration. I'm under the assumption that something happened to the stylus data for certain probes. To limp by until I had some dedicated free time I did a geometry re-qualification to get me by. (Luckily the machine with issues is primarily used in some of our more open tolerances so I was able to sacrifice accuracy) When I was able to get some free time I went ahead and deleted each styli from the stylus system one by one and added new ones with a passive qualification. Since then I've had no issues when running the passive qualification program. Be sure that the # of stylus and the name is the exact same to avoid issues. Hope this helps.

SD0 -1105 - Most times I have found the Reference Sphere Rotation Angle and Inclination Angle is incorrect, this typically applies to using an RDSXXT sensor.

My theory, since the probe can't scan without a possible collision it defaults to "Not enough points taken".

When I get this error, it's only after a Zeiss technician has calibrated the CMM. And it's on probes that have been qualifying perfectly fine before the calibration. Deleting and recreating the stylus has been my solution for many years.
