[QUOTE="tuyere, post: 371972, member: 26916"] Out of curiosity, what did it measure as? For a 20mm cube I don't tolerate more than +/- 0.1mm, but I can usually do significantly better than that. And yeah, Z heights are usually tricky because the base layers are very heavy, the trick to getting an accurate measure there is to measure from two points that are both off of the build plate. On my own cal-cube design I add a shallow groove all around the cube maybe 2mm off the print bed, and then use calipers to measure from the top edge of the groove to the actual top of the part; this way you can exclude the base layers from your measurement entirely, giving you a much more accurate feedback on 'true' Z-axis accuracy.
