After adjusting the value of Z axis above, re-connect printer with PC via Repetier-Host and put A4
paper on the hotbed. Send script 1 command again via CTRL+ALT+1. If there is no contact between
nozzle and hotbed at this time, then repeat adjusting height of Z axis as above until the nozzle touches
the glass; If nozzle has touched glass panel already, then pull the paper softly, if the paper stays still, lift
up the nozzle by clicking Z axis per 0.1mm per step until A4 paper can be pulled with a certain amount
of resistance force being felt.
with a certain amount of pressure being felt at the same time. If it is very hard to be pulled, it indicates
that the resistance force is too strong. You can lift up nozzle height per 0.01mm per step until reaching

state). Now, enter M114 in G-code and click send, the left-bottom corner of the screen will
display current coordinate value of nozzle, here we only need to know the height of Z axis, so note
down current coordinate value of Z axis and subtract that value from current value of
below picture). Then disconnect printer with PC and burn the modified firmware to main control board
of printer. Re-connect printer with PC and send script 1 command via CTRL+ALT+1, now, if Z value
reaches zero, the nozzle should be able to generate some resistance force when the paper is pulled, if it
does, it means adjustment on X axis is temporally finished.
Write down this value, value 274 in the firmware #define MANAUL
_HOME_POS_274 minus this Z value
(Note: Resistance force here means the paper can be pulled by single hand
