Before leveling, please make sure that the nozzle is clean and no residual
filaments.
1) Manual leveling
First adjust the platform to a lower position. Click Leveling, and then click
the five points in turn to level. Turn the hand nut clockwise will increase

counterclockwise will reduce the gap. Put a piece of paper about 0.1mm
between nozzle and hot bed, adjust the Z height by rotating the hand
twist nut, it is ok when feel slight drag resistance.
