At the beginning of each of my shifts, I calibrate my stylus to 0.001 mm. 80% of the time I only use it in position a0 b0. And when it shows 0.002 (or even 0.003) I start wiping everything in the world until it is 0.001. Sometimes it takes a long time. How do you solve this problem?
Do you need it THAT tight? 2 or 3 micron std dev is ok. What size probe(s) do you use? The longer/larger the probe, the larger the standard deviation, typically. Vibration will also affect the std dev.
