4. Adjust the gap: Fine - tuning the " gap" to make the gap size about 0.1 mm meet the printing
requirements, moving the extruder to the other three corners of the heating bed, and sequentially adjusting
the spring compression of the four corners of the heating bed in one direction ( clockwise or
counterclockwise ), so that an A4 paper ( about 0.1 mm ) can pass through this gap and feel a slight
resistance, and there is no scratch on the platform when moving the extruder.
When adjusting the amount of spring
compression, press the heating bed by hand and
screw the nut by hand at the same time.
Note: turning the nut counterclockwise is tight and turning the nut clockwise is loose.
