2 Lifting the build plate to the top of the Z‐axis. Go to menu "Prepare" ‐
choose "Auto home" in the LCD, the extruder/print head will go to the
original point, the build plate will go up to the top of Z‐axis.
3 Now, begin to adjust the four corners.
Use a name card between the extruder and the hot bed, move it back
and forth. You should feel some friction on the card but still be able to
easily pass the card between the plate and the extruder nozzles
without tearing or damaging the card.
If the friction is too big, it means the gap between nozzle and plate is
too small, you need to reduce plate height by loosening the screw.
On the contrary, if almost no friction, it means the gap is too big, you
need to increase plate height by tightening the screw.
4 Adjust next three corners in anti‐clockwise direction by same
method.
5 Do adjust all four corners repeatedly at least 3‐4 times to ensure the
best gap you get.
