Safety Precautions
1) The temperature of the nozzle parts can reach 250 °C during the
operation of the machine. To ensure your safety, it is forbidden to touch
the model and nozzle directly with your hand while the printer is
printing or cooling.
2) During the operation of the machine, it is forbidden to reach into the
machine to prevent pinching.
3) The working voltage is 110~220V AC voltage 50HZ/60HZ AC. The
three-pin socket should be grounded. Do not use other power sources to
avoid damage to components or fire, electric shock and other accidents.
Note: Before powering on, please check whether the input voltage value
of the switching power supply meets the voltage standard of the country
or region.
4) When the machine is working continuously for ≥ 96 hours, it should
be stopped for 1-3 hours.
Consumables
The consumables are not used after unpacking or for a long period of
time after the print model is completed. The consumables should be
taken out of the printer and sealed to prevent the consumables from
being exposed to the air for a long time, causing moisture and affecting
the print quality. At the same time, when the consumables are removed

2
The front end of the consumable should be fixed on the tray to avoid
consumables and affect the next print.
To use this printer, it is recommended to use the supplies provided by
the company. At present, the quality of consumables sold in the retail
market is uneven, and printing is prone to breakage.
Staggering and clogging the printer nozzle, etc., and irreversible damage
to the heating components of the nozzle, the extrusion motor and the
extrusion gear. The company will not guarantee the printer due to the
use of consumables other than our company.
Environmental requirements
Temperature requirement: 10°C~30°C, humidity requirement: 20%~50%,
this 3D printer can work normally within this range; beyond this range,
this 3D printer will unable to achieve the best print results.

（5）leveling method
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.

16
Layer thickness：0.1~0.4mm available. 0.1mm high precision but long printing time, 0.4mm low
precision but printing time is too short, in general select 0.2mm.
Shell thickness: 0.4mm is very thin, in general select 1.2mm,that will increase printing time.
Enable retraction: To prevent the wire from leaking when printing quickly, otherwise it will affect
the appearance.
Bottom/Top thickness: In order to make the top layer print more perfect and flat bottom layer.
Fill density: If the intensity is not high, select 20%. If the intensity is high, increase it and the
printing time also will increase.
Print speed: Generally set 30-100, he print speed is higher and the precision is lower.
Printing temperature: Depends on the filament, generally select 190 ~ 210 degrees.
Support type: Include half-support and full support. In general the model with suspended
structure needs to set support, but surface will be rough after removing support.
Platform adhesion type: "None" means do not set any support, "Brim" increases the bottom
area. "Raft" base makes the model more adherent. To make the model better adhere to the base,
add a base or edge. But best to increase a base and a edge relative to the small bottom area.
Diameter: 1.75mm
Flow: 100%

17
Nozzle size: 0.4mm.
Retraction Speed: The speed of retraction when printing.
Retraction distance: The length of material retraction, generally select 4.5~8mm.
Initial layer thickness: The first layer thickness of printing. Select default option.
Initial layer line width: 100% will be thicker and denser, Select default option.
Cut off object bottom: The length of cutting off the bottom of model.
Dual extrusion overlap: 0.15mm. Select default option.
Travel speed: The moving speed when nozzle does not extrude filament.
Bottom layer speed: The speed of printing the first layer. Setting a slower speed to make object
better attached to base plate.
Infill speed, Top / bottom speed, Outer shell speed, Inner Shell speed: Select default option.
Minimal layer time: Select default option.
Enable cooling fan: To cool the temperature of nozzle.

D．Operation for online printing
1. Power on the printer, connect USB to a
computer, the driver will be installed automatically.
If it doesn't install automatically, find the driver
under the driver folder and install it manually.
