Please follow the guide of the machine to record three different points to define a plane parallel to the heated bed, these three points must
be recorded in order with nozzle in the areas shown in the drawing below, one in each. The calibration requires to be set only for the first use.
3.1 3-Point Leveling
Operation steps:
A4 paper
Heated bed
Press the “3-point leveling mode
initiate/Point recording” button to
record Point ①, The nozzle will
automatically go to a position right
above Point ②after successful recording
Do the same height adjusting and point
recording steps to record Point ②and ③.
After successful leveling, the machine will
home again and exit 3-point leveling mode
5. Friction status of the three points should be as uniform as possible. Pay attention when traveling the head downward, especially when the nozzle is getting too close to
the bed. Even though the height detect protection will take effect and force the machine to go 0.06mm each press, the heated bed may also get burnt if you continuously
move it downward without testing the height with a piece of paper.
4. The recorded points will not be lost after power-off. But, once entering 3-point leveling mode, previously recorded points will be cleared automatically.
3. Only Z coordinates will be recorded, so all you need to do is adjusting the height with a piece of paper.
2. 3-point leveling mode can only be entered with 3D printing head connected.
6. A re-assembled machine should be re-levelled.

Fine tuning:
This function allows users to fine tune the zero of Z-axis according to bonding status of the first layer, in case the zero point is not
satisfactory after standard setting procedures. For instance, if the zero point is too high and causing bonding failure of the first layer:
Press the “Zero point updating”
button to fine tune the zero point
with the value you set. The machine
will home again after successful updating
Press “ - ” button to set a
negative fine tuning value
Note:
1. Only the zero of Z-axis need to be set and recorded. Zeros of X-axis and Y-axis are system
default values and will not and cannot be changed.
5. If your printer prints in the mid air, the zero point must be wrongly set. After correct zeroing and
homing, the coordinate of Z should be about 100.
6. Please be prudent with the “Zero point updating” button, pressing it will change zero point of the
machine. If the fine tuning value remains 0, the operation will record current height of the nozzle
as zero point. If the fine tuning value is not 0, the operation will update zero point of Z-axis using
fine tuning value you set.
4. The zero point will not be lost after power-off, so there’s no need to reset it. However, the zero
point may be deviated and needs to be reset after the reassembling.
2. Too high Z-axis zero position will lead to loose bonding at the bottom, causing the model falling
off, and too low position will make it difficult to take off the model or even scratch the heated bed.
Dedicated fine tuning is always required to obtain satisfactory first several layers. If the zero
point is too high, please use a negative fine tuning value and use a positive fine tuning value if
the zero point is too low.
3. Pay attention when moving the head downward, especially when the nozzle is getting too close
to the bed. Even though the height detect protection will take effect and force the machine to go
0.06mm each press, the heated bed may also get burnt if you continuously move it downward
without testing the height with a piece of paper.

Description of key profile settings:
Note:
①Layer Height: For the height of each layer of printing, smaller value will produce finer
surface, but cost more printing time. Suggested range is 0.05 to 0.3, not exceeding
3/4 of the diameter of the nozzle. MOOZ used 0.4mm nozzle, means not exceeding 0.3.
③Top/Bottom Thickness: Determine the bottom/top thickness of the model.
④Infill Density: Determine the filling density of the internal grid of the model, generally set
at 15% or less.
⑤Printing Temperature: Need to be set according to filament type. Suggested value for
PLA is 200~210℃.
⑥Build Plate Temperature: Need to be set according to filament type. Suggested value
for PLA is 60~70℃.
⑧Support Placement: If the model has any hovering part, the option must be switched on.
Generally, "Everywhere" indicates that support can be added on the model itself. If you
select "Touching buildplate", it indicates that support can be added only between the
print platform and the model hovering position, not on the model.
⑦Travel Speed: Travel speed should be set no greater than 40mm/s, otherwise the
Z linear actuators may lose some steps when traveling downward from home position
too fast and cause zero point deviation.
⑩Spiralize Outer Contour (i.e., vase mode): Only the outer surface and the bottom of the
model are printed, and continuous spiral lift will appear when printing the outer surface,
which can improve the surface quality, but has requirements for the model, and that is,
the model can only have one outer surface and can not be hovered.
②Wall Thickness: For the printing thickness of the outer surface of the model, the setting
of 1.2 indicates that the outer surface will go three rounds, since the width of each
round equals to the diameter of the nozzle, namely 0.4.
1. Hover the mouse over the option, and the corresponding hint will appear.
2. Right-click anywhere within the parameter setting area, you can “Configure setting visibility”.
3. Tutorial video for using Cura is available on our official website.
⑨Build Plate Adhesion: "Brim" indicates that a few layers of outer ring should be added on
the bottom edge of the model so as to prevent warping. And "Raft" is used to get the
whole model raised by adding a raft-like base on the bottom when the heated bed
leveling status is not satisfying.

3.4.4 Configuration of Color Mixing Scheme
1. Switch mixing mode
1. If only one color block is configured and the others are left empty, the whole model will print with the very one color you configured regardless of the height
parameter.
Note:
2. If you only want to use one or two of the three filament rolls, always set percentage of the filament you don’t want to use to 0 when configuring.
3. Due to the uniformity of color mixing, there will be a partial gradient transition between actual layers.

The machine adopts CMY subtractive color mixing model, wherein C stands for Cyan, M stands for Magenta, and Y stands for Yellow. For
gradient mixing mode, the gradual color changing process will follow the CMYK chromatography in general. You can use image-editing software,
Photoshop for instance, for accurate color configuration.
Note: The principle of color mixing is only for reference. Due to the
non-real-time and uniformity of color mixing, the color of actual
printing will be slightly different from the theoretical
setting.

Troubleshooting
IV
4.1 3D Printing Failure
Q : Print center is at left-bottom
corner of the heated bed
A : Check if the zero point is appropriate. Methods:
1. Check if coordinate of Z is about 100 after homing operation.
2. Move Z coordinate to 0 manually and check the friction status with a piece of A4 paper.
Q : The machine prints in the air
after file execution
A : 1. Re-level the heated bed.
2. Heated bed is too far from nozzle, result in loose bonding: Zero point is too high, reset or fine tune it.
Refer to Section 3.2.
3. Heated bed is too close to nozzle, result in squeezing, scratching and extruder step losing issues:
Zero point is too low, reset or fine tune it.
Q : Poor first layer
A : Please set the zero point correctly, increase heated bed temperature, and make sure the first layer is
successful before leaving.
A : 1. Check if the filament is stuck by the filament roll support.
2. Check if the extruder can feed normally at standby state.
3. Reinstall the filament.
4. Open the Gcode file with text editor and check if there is any garbled codes at the end of the file.
Q : Fail to finish the print
A : 1. Check and make sure all cables are properly connected to the right sockets.
2. Check if the nozzle temperature is normal, displaying “0” means unable to read nozzle temperature.
In this case, please use the spare temperature sensor to decide if the failure is caused by faulty
temperature sensor. Refer to Section 4.4 for maintenance.
Q : Unable to control X/Y/Z
movements
4.2 Whole Machine Failure
A : Wrong machine setting in slicing software, the “ Origin at center ” box must be checked, refer to
Section 3.4.2.
Q : The print falls off from the
heated bed
Q : Unable to read Gcode files in
U disk or microSD card
A : 1. Check if the file system format of your U disk or microSD card is FAT32, and with capacity not greater
than 32GB.
2. Check if the Gcode files are stored in the root directly.
3. Reboot the machine, unplug and plug the U disk or microSD.
4. Please use qualified U disk or microSD.

A : Check if the temperature sensor falls out of the heating block. Refer to Section 4.4.
Q : Able to heat nozzle, but unable
to reach target temperature
Q : Abnormal nozzle temperature,
displays “0” other than ambient
temperature
Q : Unable to preheat the nozzle
A : 1. Check if the extruder motors are working normally.
2. Refer to Section 4.4 for maintenance.
3. Please do not mix-use filament of different type or brand.
Q : Unable to extrude filament
normally
4.3 3D Print Functional Module Failure
A : 1. Unplug the cables, U disk and microSD card orderly, restart the machine to decide if the failure
is caused by corresponding faulty component.
2. Update the mainboard firmware.
3. Update the touch pad firmware.
Q : Unable to exit “starting...”
interface after power up
A : Unplug the cables, U disk and microSD card orderly, restart the machine to decide if the failure is
caused by corresponding faulty component.
A : 1. Unplug the cables, U disk and microSD card orderly, restart the machine to decide if the failure
is caused by corresponding faulty component.
2. If the issue is solved after unpluging the heating rod socket, please check if failure is caused by
short-circuit of heating rod cables. Refer to Section 4.4 for maintenance.
A : Check if the heating rod and heated bed are reversely connected.
Q : Buzzer on after starting,
the machine shutdown a few
seconds later automatically
A : 1. Check and make sure the cables are in good connection.
2. Check crossly(i.e. connect X-axis linear actuator to Y port and Connect Y-axis linear actuator to X port
and Connect) to decide if the failure is caused by the faulty linear actuator or control board.
A : 1. Check if temperature sensor cable is connecting to the correct socket properly. Refer to Section 4.4.
2. Use the spare temperature sensor to decide if the failure is caused by faulty temperature sensor.
Refer to Section 4.4 for maintenance.
A : 1. Check if nozzle temperature displays normally.
2. Check if the heating rod cable is connecting to the correct socket properly. Refer to Section 4.4.
3. Functional module is damaged.
4. Heating rod is damaged.
Q : Unable to start the machine,
auto shutdown or restart
Q : Auto shutdown after pressing
nozzle heating button
Q : Movement of X/Y/Z linear
actuator is abnormal
A : Carbonized material will accumulate in the nozzle after long time printing. To keep the print head in good
condition, we suggest you clean the nozzle after every 1kg filament printing by applying the cold-pull
method: Remove all three quick pipe connectors from the print head, then heat nozzle to 200~220℃,
use your hands to feed filaments into the three channels simultaneously until all three filaments flows out
for 5~15s. Stop heating and wait until nozzle temperature drops to 90~100℃, then pull out the filaments,
in this way, the carbonized material may be pulled out together. Remove the bulged end and be ready for
the next cold pull.You may need to perform the cold-pull 4~5 times to get the nozzle fully cleaned.
Q : Under extrusion, too little
filament is extruded during
printing
