I have my printer working pretty well except for one issue. My prints come out about 90% the height they should. I've checked my Z axis calibration. I measured the height of the carriage off the print bed, then sent a command to raise it 80 MM and then checked that it moved exactly 80 MM.
I also checked the calibration of my extruder by placing a post-it note on the filament, sending a command to extrude material, and then ensured the post-it moved exactly the distance that I told it to extrude. I'm getting nice even flow and the parts look great. My X and Y axis are perfect.
Any suggestions?
