2. Leveling: Before starting the leveling process, heat the bed to 60℃
and wait for 20 minutes. This allows for thermal expansion of the glass
to stabilize, ensuring accurate leveling.
Note：
1. Z-calibrate, Auto-leveling, XY offset and Z height diff must be
performed after replacing the nozzle, hotend, or removing/reinstalling
the extruder.
Printing Tips:
If the bed calibration temperature is set to 60°C. Before printing, keep
the bed temperature at 60°C and wait for 20 minutes to ensure
optimal first layer adhesion and print quality.
1. Z Calibrate
Click "Z Calibrate"
Click "Start" , wait Z axis calibrating
and click "Accept" and confirm
Put an A4 paper between the nozzle and
heated bed.

While moving the A4 paper back and forth,
adjust and . When you feel slight
resistance as the paper moves, you can click
the to save.
2. Auto Bed Leveling
Click to save the value, the
printer will reboot automatically.
Click to start auto-leveling,
which will take approximately 3 minutes
Click "Leveling"
Tips: It is better to heat up the bed to
the target degrees and keep it warm up
for 5-10 minutes before leveling.
10
3. XY Axis Offset Calibration
Tips: Wipe the nozzle clean before calibration to avoid any interference during the process.
Printing Tips:
1. Bed Leveling Frequency:
It is recommended to perform bed leveling every 20–25 print jobs. The Frequent
removal and repositioning of the glass bed can gradually lead to positional
deviation. Timely leveling ensures consistent print quality.
2. How to Determine if Leveling is Needed during printing:
Carefully observe the first layer when starting a new print. If there is a large gap
between the filament and the heated bed, poor adhesion, warping, curling, or
uneven extrusion (e.g., some areas too thick, others too thin, or broken lines), it
indicates that bed leveling is required.

corresponding tube and push it until it cannot be pushed anymore. The internal gears will
automatically pull the filament in.
2. When the gears stop moving, the filament may still remain inside the tube. We need heat up the
nozzle to target degrees and then load the filament.

Click Fine-tuning
Select the distance at 0.02 and
increase the Z-offset until the

The final result after adjusting
Printing Tips:
During printing, if the model is too close to or too far from the build plate, you can
use the fine-tuning function to adjust the nozzle height:
1. Tap "Fine Tune".
2. Select a tuning step of 0.02, then use Z+ (raise the nozzle) or Z− (lower the nozzle)
to adjust the height until the extrusion lines are evenly laid and properly aligned.
Proper fine-tuning helps achieve optimal first-layer adhesion and print quality.
The first layer very important
1. There are gaps between each lines, that means the Z-offset
need to be lower.
2. There are waves on the printing surface, that means the Z-
offset need to be higher
Explain:
1. Resume printing after power off
2. Resume printing after filament run out
Printer will pause printing, and
yellow light up.
Replace new filament into the
extruder, click load till the filament
was feed out.
Click “Resume” , continue to
print from the point of interruption.
8. Resume Printing
Note:
1. If the printed height is less than 1 mm, resume printing is not supported.
2. Prior to resuming the print, verify whether the nozzle has dropped. If so, use the "Force Move" function to position it
approximately 0.1 mm above the model surface.
3. After resuming the print, closely monitor the printing process and adjust the Z-offset via fine-tuning if necessary.

Double extrusion: Start the Prime tower
Because there is always one printer in standby mode during the printing process, it is easy to
cause defects such as wire drawing and material leakage. Prime tower can solve this problem,
the extruder will print a prime tower before each layer printing. Any material leakage will be
printed on the tower, effectively avoiding the phenomenon of material leakage when replacing
the extruder.
If you want to print the following two modes, we recommend adding this option to your Gcode.

1. Do not allow PET-GF, PET-CF, PA12-CF, HTPA-GF, HTPA-CF, or S-Multi to absorb moisture.
1. Dry the filament before printing as long as you are not sure if the filament is damp.
2. After drying the filament, please store it in filament cabinet with driers
3. If the printer will not be used for an extended period, please store the filament in a sealed container, preferably in a dry
cabinet.
2. Avoid PLA-HF/PETG-HF clogged during printing
1.When printing PLA with a bed temperature above 45 °C, open the front door to prevent heat buildup and extrusion issues.
2.When printing PETG with a bed temperature around 70 °C, open the front door to prevent overheating that may cause
extrusion issues or nozzle clogging.
3. To prevent warping, take caution when printing with ABS-HF, PA12-CF, HTPA-GF, HTPA-CF, ABS-
GF25, ABS-CF20, HtPA-GF25, and HtPA-CF25.
If the model size is large and the fill rate is set high, such as 60% (the default value is 15%), warping occurs and it can be
adjusted down appropriately. In addition, change the fill pattern to a spiral to reduce the risk of shrinkage. For some
structural parts with high strength requirements, you can set 5 layers of walls and a fill rate of about 25%, and try to avoid
using a fill rate of more than 50% to reduce the shrinkage tendency; for most non-structural parts with low strength
requirements, you can directly select the default 2 layers of walls and a fill rate of 15%.
1. Set the nozzle temperature to 250–300 °C.
2. Manually unload the remaining high-temperature filament.
3. Load the new low-temperature filament and manually extrude it.
4. Continue extrusion until all residual high-temp material is flushed out and the new filament flows smoothly.
5. Lower the nozzle temperature to 220–240 °C, and continue extruding while the nozzle cools down to ensure smooth flow
of the new filament.
If extrusion fails during the flushing process, increase the nozzle temperature and consider using a cleaning needle to clear
the nozzle
11. Printing Tips for different filaments
10. Maintenance and Care
Hotend:
If you print high-temperature materials or engineering materials for a long time, the inner wall of the hot end will gradually
carbonize, which will ultimately affect the extruder out of the material is not smooth, if you find that the model has a fault or
spitting material is not uniform, it may be this reason.
Replacing Filaments:
Timely replace filaments based on the type and actual usage. It is recommended to use filaments recommended by the
manufacturer. Seal filament not in use for an extended period, as excessive exposure to moisture in the air can make the
filament brittle.
PEI plate:
Please avoid touch the PEI bed by hand. It can be cleaned by dish soap with warm water and dry it by a clean cloth.
Regular Lubrication:
Once every 3 months. Home the printer first and grease it and move the Z+ to the top, then home the printer and grease again
until the screw rods full with the grease, after that clean the excess grease. If there are noise during moving. You can grease
the oil on the idler wheels when there are noise.
Software Updates:
Regularly update the printing software to improve print quality and efficiency.
4. After printing with high-temperature materials such as PA-CF, PET-CF, or PET-GF, and before
switching to low-temperature, lower-hardness materials like PLA or PETG, it is recommended
to follow these steps:
