¶ 1. Tools:
S2.0 Allen key
¶ 2. Disassembly Steps:
¶ Step 1: Turn off the Device
Before replacing the sensor, make sure to turn off the device and disconnect the power for safety.
¶ Step 2: Remove the PEI Board
Manually move the heated bed to the front of the device for easy disassembly. Remove the PEI board from the heated bed.
¶ Step 3: Disassemble the Offset Measurement Switch Module
①Use the S2.0 Allen key to loosen the 2 screws securing the offset measurement switch module.
②Slightly move the offset measurement switch outward and unplug the 2 wires. Remove the offset measurement switch module.
¶ Step 4: Remove the Y-Axis Accelerometer gyroscope module
Use the S2.0 Allen key to loosen the 2 screws securing the Y-Axis Accelerometer gyroscope module.
Remove the Y-Axis Accelerometer gyroscope module.
¶ 3. Installation Steps:
¶ Step 1: Install Y-Axis Accelerometer gyroscope module
Align the new Y-Axis Accelerometer gyroscope module with the positioning groove and screw holes on the offset measurement switch.
Use the S2.0 Allen key to tighten the 2 screws.
¶ Step 2: Install the Offset Measurement Switch Module
①Plug in the offset measurement switch wires (2PIN) and Y-Axis Accelerometer gyroscope module wires (7PIN) into the offset measurement switch module.
②Align the screw holes of the offset measurement switch module with the heated bed's screw holes.
Use the S2.0 Allen key to tighten the 2 screws, ensuring the offset measurement switch is level with the heated bed.
¶ Step 3: Install PEI Board
Reattach the previously removed PEI board along the edge of the heated bed.
¶ 4. Calibration Steps:
After replacing the Y-Axis Accelerometer gyroscope module board, it's recommended to perform automatic leveling calibration and vibration compensation calibration.
¶ 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.
