Z Height calibration for Original Prusa i3 MK2

thingiverse

Original Prusa i3 MK2 auto mesh bed leveling is great, but it has its flaws. The V2Calibration.gcode that comes with it doesn't use the entire print bed and fails to draw long Y lines. This means your bed's small height variations will impact prints that cover the whole bed, which V2Calibration.gcode won't show. These tests are similar, but they differ in a few key ways: they use the full bed, separate tests for X and Y lines, and follow usage instructions below.

Print Z-Height_Calibration_X.gcode. If either side is too high or low, adjust them at Calibration > Bed Level Correct menu. Repeat step 2. Print Z-Height_Calibration_Y.gcode. If either top or bottom side is too high or low, adjust them at Calibration > Bed Level Correct menu. Repeat step 4. Notes for the provided gcode files: Don't perform live Z calibration with it, as it doesn't contain the command G87 and the calibration won't be saved (you can edit the files and add G87 at the beginning if you wish). Bed / nozzle are warmed up after mesh bed leveling. Nozzle will lift to top middle in the end.
