Bed Level Correction Calibration Squares
thingiverse
The Original Prusa MK2 has a "Bed Level Correction" calibration setting where one can virtually set the nozzle on Left/Right/Front/Back sides to correct for minor differences in first layer up to 50 microns. This is a .2 high print so only one layer will be printed with a .15 initial layer. To use, I print out initially where one square is perfect (by adjusting Live Adjust Z calibration). Then I check the opposite square and saw the separation between filament lines. It could be ripped easily indicating not enough squish. In the calibration settings I virtually lowered the nozzle by 15 microns (-.15). Eventually I was able to determine that with a left side bed level correction set to -.35 all 4 outer squares (and center square) printed with an equal squish. Further Live Adjust Z will set all sides equally going forward.
