Calibration. Different results

I greet you all, colleagues.
I have a small problem that tends to come and go when calibrating angles. I work with many styli and use a 9-slot magazine for this. Each stylus has about 10 different angle positions. When I did the calibration, two angles on different probes were out of tolerance. One probe has a CM25-2 probe and the other CM25-3. And at the same time, PSDMIS accepts the calibration result without asking the operator. The next day I did a similar calibration and the result was OK.And always out-of-tolerance angles equal to A90 or more than A90 It is very strange . I have been working in this mode for 3 years and there were no such problems. And this year it started. I check the probes visually and do the cleaning before each calibration the same way always. What could be the problem ?

  • I compared 4 calibration reports from this year in different months. My reference sensor has stable deviations from EFT (X -0.005 Y - 0.078 Z-0.264) Stability indicates no problems, but is the deviation on the Y axis and especially on the Z axis too large? I don't understand what this deviation means? I assume that on the main probe, the XYZ THEO and XYZ MEAS coordinates should match and be the same? What do these deviations say? {"data-align":"none","data-size":"large","data-tempid":"temp_23122_1659593814994_576"}


    When you calibrate with the "master probe", you should select "reset to theo", and select "yes, the sphere moved", so that the deviations on the master probe are zero...
    Then, you will have to re-calibrate all the probes Disappointed...
