¶ 1. Tools:
S2.5 Allen key
S2.0 Allen key
Open-end wrench
¶ 2. Disassembly Steps:
¶ Step 1: Power Off the Device
Before replacing the X-axis pulley, ensure that the device is powered off and disconnected to ensure safe operations.
¶ Step 2: Remove the Print Head
① Pull the Z-axis synchronous belt to lift or lower the print head to the middle position of the Z-axis for subsequent disassembly.
Note: Pulling to the right raises the print head (red arrow direction), pulling to the left lowers the print head (yellow arrow direction).
② Use the S2.5 Allen key to unscrew the 4 screws securing the print head module and place the print head aside.
As there is no need to disconnect the wires and PTFE tube on the print head, the movement range is limited. Just ensure it is within the active range.
¶ Step 3: Disassemble the X-axis Belt Tensioner
① Rotate the red knob on the X-axis belt tensioner counterclockwise and remove it, placing it aside for later installation.
② Use the S2.0 Allen key to unscrew the front and rear 2 screws securing the X-axis belt tensioner and remove the X-axis belt tensioner housing.

¶ Step 4: Remove the X-axis Sheet Metal
① Use a tool to remove the belt copper buckle at the front of the X-axis sheet metal and take down the pulley assembly wrapped by the belt, placing it aside.
 |
 |
 |
② Slide out the X-axis sheet metal from the direction of the X-axis tensioner and remove the X-axis sheet metal.

¶ Step 5: Disassemble the X-axis Pulley
Use an open-end wrench to fix the nut, then use the S3.0 Allen key to counterclockwise unscrew the 3 spacer screws securing the pulley, and remove the pulley, screws, spacers, and nut.
¶ 3. Installation Steps:
¶ Step 1: Install the X-axis Pulley
① Take out the new X-axis pulley and install it with the previously disassembled screws and spacers.
② Install the newly assembled pulley assembly onto the X-axis sheet metal.
Take out the previously disassembled nut, screw it onto the screw, fix the nut with an open-end wrench,
and then use the S3.0 Allen key to clockwise tighten the screws one by one.

¶ Step 2: Install the X-axis Sheet Metal
① Slide the X-axis sheet metal in from the X-axis tensioner.
③ Take out the previously disassembled pulley assembly, pass the belt through the pulley assembly,
and install the copper buckles at both ends of the belt onto the X-axis sheet metal of the print head module.

|
 |
¶ Step 3: Install the X-axis Tensioner
Take out the previously disassembled X-axis tensioner housing and screws, align it with the screw holes, and install it on the device.
Use the S2.5 Allen key to pre-lock the screws.
|
|
|
¶ Step 4: Install the Print Head
① Take out the previously disassembled print head and screws placed within the active range,
align them with the screw holes on the X-axis sheet metal, and use the S2.5 Allen key to tighten the screws one by one.
② Check if the print head is shaking. If there is any movement, adjust the hex eccentric spacers below the print head until it slides smoothly and does not shake.
¶ 4. Adjust the X-axis Belt:
Take out the previously disassembled X-axis tensioner knob, clockwise rotate the X-axis tensioner knob to tighten it to the maximum,
and then counterclockwise rotate it one full turn.
¶ 5. Calibration Steps:
After replacing the X-axis pulley, it is recommended to calibrate the device according to the following instructions.
¶ Step 1: Power On the Device
Connect the device's power cord, press the power switch on the side of the device to start it.
Note:
When inserting the power cord, please avoid crossing it with the print head cable to prevent interference.
¶ Step 2: Calibrate the nozzle position
In the main interface, click on the "Tools" icon ➜ "Control" icon ➜ "Module Calibration" ➜ "Position Calibration."
The machine will automatically perform detection and pause near the top the calibration module.
You could adjust the nozzle to the center position of the calibration module using the distance units and X/Y axis movement direction on the interface.
Once done, click "Save," and finally, perform the automatic leveling again.
¶ Step 3: Automatic Leveling Calibration
On the device's main interface, click the "Tools" icon - "Control" icon - "Auto- Level" - "Confirm" to start the leveling process.
Follow the set process, and after leveling is complete, click "Finish." This process takes approximately 15 minutes.
Note:
① Please check whether the PEI board is installed before leveling.
② The leveling sensor is only used for platforms with metal surfaces.
If you replace the printing platform by yourself, please choose a platform with a metal surface to ensure the normal use of the automatic leveling function.
¶ Step 4: Vibration Compensation Calibration
On the device's main interface, click the "Tools" icon - "Control" icon - "Vibration Compensation" - "Confirm" for resonance detection.
Follow the sequence to detect the X and Y axes. Click "Finish" after the Y-axis detection. This process takes approximately 15 minutes.
Note:
① Place the printer in a spacious and stable area during vibration compensation to avoid interference from other resonance sources.
② There may be significant noise during the vibration compensation process, which is normal.
