of the switching power supply meets the voltage standard of the country
or region.
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.

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.

F． FAQ
1. Copy these two files to the SD card
2. Then restart the machine and wait for
the machine progress bar to complete
before the firmware is refreshed.
3. Then the user needs to delete the two
files in the SD card to be used normally,
otherwise the firmware will be refreshed
every time the phone is turned on
1. After the machine nozzle is heated, the
consumables are normally fed into the
feeding mechanism by hand, and then
passed through the Teflon tube to enter the
nozzle.
2. When it is found that the gear of the
feeding mechanism emits a "beep" sound, it
can first check whether the consumables
are wound, causing the extrusion
mechanism to pull the material.
3 If this is not the reason, raise the machine
nozzle and use the 0.4mm needle in the
toolbox to insert it from below the copper
nozzle and rotate while inserting.
4. Under normal circumstances, this needle
can be used to open the copper nozzle, so
that the feed is smooth. The reason for this
blocking is generally that there are
impurities in the consumables, which leads
to plugging.
Question1: How to update the firmware?
Question 2:What if the filament does not discharge from the
machine?
35
Question 3: When the machine returns the filament, it can't be
1. Before returning the material, please
heat the nozzle first, and then withdraw
the consumables as soon as possible. If
you can't pump it, you can re-feed the
material with the advanced material,
and melt the extruded block formed at
the end of the consumable in the
nozzle.
2. When withdrawing the
consumables, before the end of
the consumables reaches the
pneumatic joint, we will usually
pull the Teflon directly from the
Teflon and cut the end of the
consumables.
3. Because the end of the
consumables in the nozzle will be
deformed by heat, if the end
deformed consumables are directly
pulled out, it may be stuck to the
pneumatic joint or the limit switch for
damage detection. (The limit switch
for the broken material detection is
single. Towards).
If the power is suddenly turned off when the part is first printed, the machine
will not save the print data. Unless the height of the print exceeds 0.5mm, the
power failure will be supported. If the height is less than 0.5mm, it is
recommended to reprint directly.
returned. What should I do when stuck in the pneumatic joint?
Question 4: What should I do if I cannot resume printing after
power shutdown?

Question 5: When the machine is leveling, the nozzle moves to
If this happens, the X-axis beam is generally loose. At this time, the
hex socket on the right side of the machine can be adjusted with a
wrench to adjust the tightness.
the left, it can be leveled normally. When the nozzle moves to
the right, it is found that the distance between the nozzle and
the heated bed are very far or very close. If the spring is
adjusted to the extreme position, it still cannot be leveled.
What should I do?
37
1. After the user gets the 3D printer, if the leveling is found to be curled on the
first layer of silk, it feels like it is gently falling on the platform. It can be judged
that the leveling is not adjusted, and the nozzle is too high from the hot bed. ,
2. At this point we need to re-level, the quality of the leveling can largely
determine the success rate of the part printing.
3. In addition, in order to ensure good contact between the model and the
platform, we can set the larger plane of the model face down when slicing, and
can also be set in the slicing software to add Raft to the model, which can make
the model stick to the platform. Firm.
Question 6:After the machine heats up, the filament is
discharged normally. However, when the printing is
performed for the first time, the curling occurs on the
platform. After printing several layers, the filaments get out
of the platform. What should I do?
