¶ 1. Tools:
S2.5 Allen key
¶ 2. Filament Retraction:
¶ Step 1: Raise the Z-Axis
Connect the power supply.
① In the main menu, rotate the knob counterclockwise to the indicated position and press the knob to enter the next menu.
② In the settings menu, rotate the knob clockwise to the indicated position and press the knob to enter the next menu.
③ In the axis movement menu, rotate the knob clockwise to the indicated position and press the knob to enter the next menu.
④ Rotate the knob clockwise to adjust the value to "120mm" to raise the Z-axis to the middle position.
¶ Step 2: Heat the Nozzle
Return to the settings menu, rotate the knob to the "Filament" option, and press the knob to enter the next menu.
In the filament change menu, rotate the knob to the "Extrude" option and press the knob to start the heating process.
The nozzle will automatically heat up to 215°C and begin extrusion. Press the knob to "Stop and Return" when finished.
¶ Step 3: Remove the Filament
Once the nozzle has reached the target temperature, press the handle on the extruder to push the filament forward slightly.
Quickly retract and remove the filament. Follow the sequence in the image provided.
¶ 3. Disassembly Steps:
Note: The images below are for better illustration, taken by disassembling the print head from the entire device.
It is not necessary to remove the entire print head during actual disassembly. Some accessories in the images may be missing, but the steps remain consistent.
¶ Step 1: Turn Off the Device
Before replacing the extruder motor, ensure that the device is turned off and disconnected from the power.
Wait for the print head temperature to cool to room temperature for safe operation.
¶ Step 2: Disconnect Extruder Motor Cable
Disconnect the extruder motor cable.
¶ Step 3: Disassemble Print Head Casing
Use the S2.5 Allen key to loosen the 2 screws (located on the back of the print head) that secure the print head casing.
Since the print head casing and the model cooling fan (FAN0) are integrated, remove the FAN0 cable from the groove before pulling out the cable.

¶ Step 4: Disassemble Extruder Motor
Use the S2.5 Allen key to loosen the 4 screws that secure the extruder motor and remove the extruder motor.

¶ 4. Installation Steps:
¶ Step 1: Install Extruder Motor
① Take the new extruder motor, install it in the corresponding position, and take out the screws previously removed from the old extruder motor.
Note: When installing the extruder motor, ensure that the motor's port is oriented towards the left.
② Use the S2.5 Allen key to thread the short screw through the motor ground wire, align one of the screws with the corresponding hole, and pre-lock it.
Then, thread the long screw through the extruder assembly, align three of the screws with the corresponding holes, and pre-lock them.
Finally, ensure all four screws are correctly aligned with the holes and tighten all of them.

¶ Step 2: Install Print Head Casing
Take out the print head casing and screws previously removed. Insert the model cooling fan cable into the print head adapter board's FAN0 port.
Place the cable in the groove, keeping any excess cable to the side to avoid interference with the fan's rotation.
Use the S2.5 Allen key to tighten the screws by aligning them with the corresponding holes.

¶ Step 3: Install Extruder Motor Cable
Insert the extruder motor cable into the extruder motor port.
¶ 5. Calibration Steps:
After replacing the extruder motor, it is recommended to recalibrate the device according to the following instructions.
¶ Step 1: Turn On the Device
Connect the power cord to the device and press the power switch on the side to start the device.
Note:
When inserting the power cord, please avoid crossing it with the print head cable to prevent interference.
¶ Step 2: Nozzle Calibration
① On the main interface, rotate the knob counterclockwise to select the settings icon, and then press the knob to enter the settings menu.
② In the settings menu, rotate the knob clockwise to select "Module Calibration," and then press the knob to enter the calibration menu.
③ In the calibration menu, first rotate the knob clockwise to select "Position Calibration."
The machine will automatically probe and stop near the calibration module.
Observe the distance between the nozzle and the center position above the calibration module.
You can enter the axis movement interface by selecting the X/Y move distance option on the screen and pressing the knob.
Adjust the corresponding axis distance to align it with the center position of the calibration module.
Then press the knob again to return to the calibration menu. Finally, click the "Save" button to complete the calibration.
Please note that after completing the calibration, perform an automatic leveling again.
¶ Step 3: Auto Leveling Calibration
① On the main interface, select the settings icon by rotating the knob counterclockwise.
② In the settings interface, rotate the knob clockwise to select "Auto Level" and press the knob. A popup will appear; select "√" to initiate the device's preheating, nozzle cleaning, and automatic leveling process.
Note:
I. Please check whether the PEI board is installed before leveling.
II. The leveling sensors is only used for platforms with metal surface.
If you replace the print platform yourself, please choose a platform with a metal surface to ensure the normal use of the automatic leveling function.
III. This PEI sheet can be used for printing on both sides, but you need to follow the following rules:
If you level the bed using side A, then you should also print on side A. If you switch to side B, you will need to re-level the bed.
¶ Step 4: Adjust Z-Axis Compensation
I. Insert the TF card into the device's slot.
II. Select any model and start printing.
Note: After starting the print, carefully observe the first layer.
If situations ① and ③ occur, indicating a mismatch in Z Offset, you can make fine adjustments during the printing process.
Adjust the distance between the print head and the heated bed. After making adjustments, you can pause the print task (for testing purposes only).
Then, start printing the actual model file you need.
