Thanks for the demo, I wondered how to use the boards and appreciate the time you took to show us how. Can you comment on whether this should be done when the unit is brand new, or if/when they recommend doing it (what intervals?). Also maybe it's worth mentioning that there would be a thickness to the spray applied to the pins, so the scan would be the outside of the spray coating- and you measured clean pins. Perhaps this could at least partially account for the tiny difference in measurement, rather than assuming inaccuracy (in addition to any potential inaccuracy of the calipers). Very impressive results, I'm happy I own one :-)
You do not need to do this all the time on your scanner especially a new one. It is already factory calibrated. But if you find that you are having bad data or point clouds keep messing up, then this is a very easy thing to do to try and get the calibration back in order. Thanks for the other input! Happy scanning!
