NOTES
1. Do not place the printer in vibrating or other unstable environments, as
the shaking of the machine will affect the print quality. 2. Do not touch the
nozzle and heated bed when the printer is working to prevent high-temperature
burn and personal injury. 3. After printing, please take advantage of the
residual temperature of the nozzle and clean the filaments on the nozzle with
the help of tools. Do not touch the nozzle directly with your hands during
cleaning to avoid burning. 4. Please do product maintenance frequently, and
regularly clean the printer body with a dry cloth to wipe away dust and sticky
print material under the situation of power off. 5. 3D printers contain high-
speed moving parts, so be careful not to get your hands caught. 6. Children
must be supervised by adults when using the machine to avoid personal injury.
7. In case of emergency, please cut off the power directly. 8. Before
leveling, homing or printing, ensure that the golden PEI sheet is properly
placed on the platform. Failure to do so may result in nozzle collisions with
the magnetic sheet, causing damage to both the nozzle and the magnetic sheet.
9. It is essential to ground the machine during operation. Devices that are
not grounded or improperly grounded inevitably increase the risk of electrical
shock. 10. If the machine is not in use for a long period, please turn off the
device and unplug the power cord.
Troubleshooting Guide
A stepper motor of the X/Y/Z axis is not moving or making a noise when
“zeroed” The stepper motor cable could be loose. Please recheck the wiring
connection. The corresponding limit switch may not be triggering properly,
please check whether there is any interference in the movement of the
corresponding shafts and ensure the limit switch wiring is not loose. Loose
timing belt may result in rough motion or abnormal noise in the X/Y axis. It
can be resolved by adjusting the tension of the timing belt using the rotary
knob. Nozzle Head Assembly is exhibiting Extrusion Anomalies Check that the
extruder stepper motor cable is not loose or disconnected. Check whether the
set screw of the extruder gear is firmly engaged to the motor shaft. The heat
dissipation of the nozzle assembly may not be enough, verify temperatures and
check cooling fan operation. For clogged nozzles, try first heating the nozzle
to 230ºC and pushing the filament by hand to remove a potential clog, or use a
fine needle to unclog the nozzle tip while it is heating up. Model does not
Adhere to the Build Platform (PEI Sheet) or is Showing Warping The key to
whether a model can adhere (stick) to the build plate is the largely based on
the printing of the first layer. When printing the first layer if the distance
from nozzle to platform is more than 0.2mm, it will seriously reduce print
adhesion Try setting the build model first layer option in Cura to [Brim] to
improve first layer adhesion, this should also be used to reduce any cases
whereby the edges of the printed model are warping or lifting off the build
platform. Model shows signs of Misaligned Printed Layers The travel speed of
the Printer hot end assembly or Print Speed is set too fast. Please try to
reduce the Print Speed The belts of the X/Y axis may be too loose or the
synchronizer pulley is not secured tightly. Check these components. The
current to the Drive may be too low. Severe Issues in Printed Model of
“Stringing” or “Ringing” Insufficient retraction distance is causing issues,
increase the retraction distance in Cura prior to Slicing. In many cases, if
the retraction speed is too slow, you may need to set the retraction speed
higher in Cura prior to Slicing. When slicing your model, check the box for “Z
Hop When Retracted” and set the “Z Hop Height” to about 0.25mm. Print
temperature may be too high, which can cause certain filaments to become
sticky and stringy. If the printing temperature is too high, it can cause the
filament to become too fluid and sticky, resulting in poor 3D printing
quality. In this case, lowering the printing temperature slightly can help.

Supplymentary Introduction
Special Case:
l The Y-axis slider plate is adjusted at the factory, but the machine’s
pulleys may be loose due to transportation. If the printing platform is shaky
or loose, you can use an open-end wrench to slowly unscrew the hexagonal
isolation column under the platform until the Y-axis slider plate slides
smoothly without shaking!
l Similarly, you can adjust the hexagonal isolation column underneath the
printhead if it wobbles or becomes loose. There are also corresponding
isolation columns for the pulleys on both sides of the gantry that can be
adjusted.

Display Screen Operation Introduction
Operation Of The Rear Cooling Fan: From the Home Screen, select the Print
option. Next select the Fan Icon in order to adjust the cooling fan
operational settings during the printing process. NOTE: The Rear Cooling Fan
has three operational modes: Silent(60%), Normal(80%) & Sport(100%). Please
select a mode appropriate to your printing needs as shown in photos below.
The Rear Cooling Fan is turned off when selecting the Silent mode
Print Mode Introduction l During the printing process, users can adjust the
printing mode by clicking the speed icon. l The three modes correspond to
three different speed values, acceleration values, drive mute thresholds, and
percentages of fan speed
settings during printing.
10
Display Screen Operation Introduction
Vibration Pattern Optimization Introduction l It is recommended to perform
vibration pattern detection after first use or after the machine is moved or
parts are replaced. Users can
select the vibration pattern optimization option in the advanced settings. l
Vibration mode optimization is performed on the X-Axis and Y-Axis
respectively. Please do not shake the machine during the testing
process and wait patiently for the testing to complete.
11
Auto-Leveling Procedure
When first running the machine, the distance between the platform and the
nozzle needs to be calibrated in the leveling mode, which is about the
thickness of a piece of A4 paper .
l When the printer is powered on, select Level.
Note that the leveling sensor only detects the metal platform plate, for example, replacing the glass platform for leveling will not produce detection effect, which will cause the nozzle to squeeze the platform.
l Each axis of the printer automatically returns to the home position, after entering the leveling page, place a sheet of A4 paper between the nozzle and the platform, and adjust the height
compensation values using the screen controls to increase or decrease the distance between the nozzle and the platform (P2), and slide the sheet of paper back and forth several times, until
there is a slight amount of noticeable friction generated. At this point, the center point calibration will be completed. Next, select the auxiliary leveling option [
] , to calibrate the 6
corner points of the platform with the same sheet of paper by adjusting the hand-twisting nuts found under the heated bed, and once again sliding the paper until friction has been
detected and the paper can be pulled out, but not slid under the nozzle. This will complete the auxiliary leveling calibration.
l After completing the manual auxiliary leveling process above, next select the automatic leveling option from the menu and your printer will begin the automatic calibration process. [
]
l Your printer will enter a heating state during the automatic calibration process as the nozzle is heated to 140ºC and the heated bed to 60ºC (Please adjust the heated bed temperature to
the recommended temperature of the filament you intend to use to ensure accurate leveling values) .
l After reaching the preset temperature, begin the 36-point automatic bed calibration.
l When completed, perform Z-axis compensation setting: Place an A4 paper between the print head and the platform. Adjust the compensation value by clicking, and gently slide the A4
paper. When the A4 paper can be pulled out but cannot be pushed in, the leveling is complete.
l Click the save icon to save.[

Model (Operation) Testing
Printhead Feeding Verification
1. First, insert the filament through the filament detection sensor and to
the bottom of the Printhead assembly. 2. Choose [Prepare] > [Extruder] > [Load
] (the temperature of the nozzle will be automatically heated to 200ºC. 3.
After the nozzle reaches 200ºC, choose the feed option to extrude filament
material from the nozzle. 4. Clean melted filament off the nozzle and heated
bed before printing.
NOTE: Filament with different hardness have different requirements for
“spring” strength. The spring strength of the extruder can be adjusted with an
Allen Wrench(within 2.0mm). When turning counter-clockwise, spring strength is
increased, while spring strength is decreased when turned in a clockwise
direction
Normal Extrusion State
Rotating the button counter-clockwise: The extrusion force increases, which means that the filament is pushed out of the nozzle with more force. Rotating the button clockwise: The extrusion force decreases, resulting in a reduction of the force with which the filament is pushed out of the nozzle.
Printing Functional Test:
The nozzle is too far
1. Insert the USB Drive into the printer’s USB port. 2. Choose [Print] from the main menu and select the desired file. 3. When the nozzle and heated bed reach the required temperatures, the X, Y & Z axis will return to Zero (Home) and begin printing.
The nozzle is too close to the platform, and resulting in under extrusion.
The extrusion
from the platform and
volume & distance the resulting adhesion is
between the nozzle insufficient. The model

NOTE: When printing the test model, please observe the first layer printing and compare against the figure on the right. In cases A and C, the compensation settings are not properly adjusted. You can make compensation adjustments during printing to adjust the distance between the nozzle and the heated bed platform. In case B, the nozzle and the platform are at the ideal printing distance and can continue printing without any further adjustments.

Adjustment of nozzle height while printing
NOTE: While printing and following this procedure for
fine-tuning the nozzle height, please ensure that you
switch the moving distance to the smaller increment
settings of 0.01mm or 0.1mm to prevent the nozzle from
potentially dragging excessively along the heated bed
platform (which can cause damage to the build plate) or
to keep filament from “hanging” in the air.
Resume Printing Function
Power Loss Recovery 1. Your printer, has features to continue printing
following a sudden interruption or loss of power (an outage) or any accidental
events (aka “switching-off” power), and this function does not need to be set
manually. 2. Once power has been resumed to the printer, simply press the
“Resume” option to continue printing. NOTE: The PEI metal build plate has
better overall adhesion when it is fully heated. If the power has been “Off”
for too long, the model may become easily dislodged or fall off the PEI plate
very easily. In such event, the Resume Printing Function will not be able to
continue.
Filament Detection When the sensor detects that filament is not present, this
function will inform you to replace the filament before continuing an active
print, in order to prevent a print failure due to insufficient filament
material.
