1.2 Cautions
1. The nozzle temperature is up to 200 ℃during the working period of the 3D printer
and after printing. So do not touch the nozzle with your hand;
2. Please follow the instructions in the guide to operate and use the machine. If you
have any questions, you can contact the after-sales department;
3. If the printed model needs to be disassembled for support, please wear gloves so as
not to be scratched by tools or supporting materials during the disassembled process;
4. In daily use,it is necessary to regularly clean and lubricate the optical axis of the cross
slide table of the 3D printer, and be careful not to drip onto the casing or belt when
adding lubricating oil.
5. Reading "User guide", at the same time with the actual operation of the machine will
be more conducive to your operation.
6. In the printing process encountered a problem with the machine print, you can first
take a photo to reflect the problem more intuitively, at the same time provide the
machine number of photos (the label at the bottom of the back of the machine), and
then contact the after-sales;

Chapter 2 Machine Packaging
2.1 Disassemble the package
Remove the foam from the machine, take out
the accessories box and filament.
Take out the power cord from the
accessory box and plug it.
"-" is power on, "O" is power off.
Click “Prepare” to enter the prepare
operation interface, select “Return to
zero”, waiting machine automatically
returns to the zero position.

Chapter 3 Adjustments to the printing platform
3.1 Coarse tuning
Select “Prepare” on the LCD screen,
and then click “Return to zero” option,
the print platform and cross slide will
return to the zero position.
When the machine returns to zero, the
motor will be automatically locked. You
need to select "Unlock stepper motor" to
unlock the motor before moving the
cross slide.
Move the nozzles around the glass plate in turn to adjust the distance between the
nozzle and the glass plat.
In coarse tuning, the approximate distance between the nozzle and the glass plate is
the interval between the two pieces of paper. If the distance is too large, the platform
nut should be rotated clockwise to make the platform upward. If the distance is too
small to touch the nozzle, turn the nut counterclockwise to make the platform down.
Rotate the platform nut counterclockwise,
and the platform down
Rotate the platform nut clockwise and the
platform up

3.2 Fine tuning
Select a model and wait for the printer to start printing, look at the print platform,
again to see the distance between the nozzle and the platform is probably a piece of
paper, and then start to print debugging platform dedicated auxiliary debugging file, the
adjust.gcode, by looking at the the effect of the first layer to fine-tune platform, print out
the first layer can stop printing, fine-tune and adjustment of the next print.
If the filament spilled out is serrated, the
distance between the platform and the
nozzle is too large, and the filament is
thrown down from the nozzle instead of
sticking tightly.
Turn the nut a little clockwise to make the
platform go up until the phenomenon disappears
and a tight line appears.
If the filament is found to be too thin or not
coherent, it means that the distance between
the nozzle and the platform is too small,
resulting in too small amount of the nozzle.
Turn the nut slightly counterclockwise to
lower the platform until the filament output is full
and smooth.
Adjust well the effect of platform printing
should be full out of the filament and the
line pressure is flat on the platform.

If the distance between the nozzle and the platform is too large or too small, please
stop printing and adjust the platform until the distance between the platform and the
nozzle is appropriate. In most cases, the printing failure is caused by the platform not
being adjusted properly. Therefore, please debug repeatedly as required to ensure that
the platform height has been adjusted to a better level. And when printing the first layer,
it's best to watch the machine print and make sure the machine prints properly before
leaving.
