4. Print Operation
4.1 Use of The Printing Platform
Step 1
1. When you receive the device,
the platform is installed, if you
want to disassemble it, please
hold the front wrench, and pull
it forward to install it, then
align the snap position and
push it inward.
Step 2
1. As shown in the picture for the
platform of the nine positioning
screws will build the platform
positioning slot aligned with the
positioning screws to push
inward can be successfully
installed
Step 3
1. Find the platform glue in the
kit, and after the platform cools
down, apply three layers to the
area to be printed: horizontal,
vertical and diagonal to warm
up.

4.2 How to Calibrate
Step 1
1. Initial leveling of the platform
before shipment, if the first
layer is printed successfully at
the first printing, subsequent
leveling steps may not be
performed
Step 2
1. When printing the nozzle is
found to be distant or close to
the platform, but the overall
flatness of the platform has not
changed, that is, the nozzle is
equal to the height of the four
corners of the platform, please
click the screen in the automatic
leveling, wait for the completion
of the 49 points of height
detection error, and then print
test
Step 3
1. When printing the nozzle is
found to be distant or close to
the platform, but the overall
flatness of the platform has not
changed, that is, the nozzle is
equal to the height of the four
corners of the platform, please
click the screen in the
automatic leveling, wait for the
completion of the 49 points of
height detection error, and
then print test.
2. Print the compensation
parameter file once after
modification and burn it to the
machine

Step 4
1. If the four corners of the
platform from the height of the
nozzle has a large gap, you
need to adjust the leveling nut
to complete the foundation
leveling, as shown in the figure
using a fixed height object,
respectively, for the four
corners of the platform to
measure the height
Step 5
1. When you can't push the
nozzle manually
2. You can click “ ” unlock the
motor
3. Push the nozzle to the four
corners of the platform to
measure the height
Step 6
1. Leveling by the nuts under the
four corners of the platform,
when the base height of the
four corners is approximately
the same
2. Automatic leveling can
compensate for certain errors
3. Ready for printing
