Turn on the machine and manually move the
nozzle to the middle of the printing platform.
Then let the z-axis go back to zero. If the copper
nozzle is far from the platform or close to the
platform or even press down the platform, raise
the z-axis. Then rotate the big head screw
pointed by the red arrow in the right picture.
Then let the z-axis go back to zero and repeat the
above actions until the copper nozzle is adjusted
to the distance of about one A4 paper from the
platform as shown in the right picture.
Click on the levelling button on the screen
and enter the levelling interface as shown below.
Click on five icons in turn to verify that the
distance between the sprinkler and the platform
is the same.If the distance is not the same, use
L-shaped inner hexagonal wrench to rotate the
four corners of the platform screw as shown in
the figure until the requirements are met.
