had an interesting experience trying the z calibration from the original post (.zip file) here.
i printed a cube in the center and also one near each corner, just to make sure i don't break the calibration anywhere on the plate.
they were mixed, 0.9 to 1.5mm off, but i didn't want to re-level since its been working well, so i just used the smaller 0.9mm to change the zeroing with.
i followed the procedure, printed the .gcode enabling the zero option, removed build plate, homed, moved it up by 0.1 increments 9 times then hit the z=0 button.
re-printed the 5 cubes, and one didn't print. probably due to my lack of calipers (so 0.9 was a bit too much in that corner), which i hope to fix some day. ok, the rest were indeed much better heights, so i figured i'd just adjust back 0.2mm.
i removed build plate, homed, moved _down_ 0.1 increments twice, then hit z=0. reprinted the cubes... they were all back to the original heights, 0.9 to 1.5mm off.
i suspect there is something else going on introducing variability in the Z axis? or does the Home button not go to the last z=0 position?
