I have this problem, and i need to now if someone else have the same or have found any solution. I have a tip 0.5 diameter and lengh 3mm. when i go for the calibration, the default routine does not can run, because when goes for the level points it hit the stem and not the tip cause of the small length. i try some things like 3d calibration where i set 25 points and 4 levels, but then the calibration is exceeded the limits.
