Long-term use inevitably leads to wear and tear on some parts. Regular maintenance can mitigate this wear and prolong the lifespan of the machine while enhancing its operational performance. We can maintain the machine in the following ways:
Maintenance and Lubrication Steps for the 3D Printer’s Z-Axis Lead Screw
Regular Inspection and Cleaning:
- It is recommended to inspect and clean the Z-axis lead screw every three months.
- If the printer is used frequently, it is suggested to perform this check monthly.
Pre-Lubrication Cleaning:
- Before lubricating the Z-axis lead screw, it is essential to remove any dust, impurities, or plastic particles.
Lubrication Process:
- Use specialized lubricating grease to apply a thin, even layer on the lead screw.
- The operation steps are as follows:
- Home the print bed to the highest point.
- Apply a thin layer of lubricating grease to the lead screw.
- Move the print bed to a lower position.
- Repeat this process to ensure the lubricating grease is evenly distributed along the entire Z-axis lead screw.
Re-zeroing and Cleanup:
- After lubrication is complete, re-zero the Z-axis.
- Clean up any excess lubricating grease around the lead screw nut to prevent contamination and affect print quality.
Precautions:
-
Use the correct lubricating grease and avoid using too much to prevent attracting dust or affecting printer performance.
-
During operation, be mindful of safety and avoid contact between the lubricating grease and areas other than the printer’s moving parts.

3D Printer X/Y Axis Guideway Maintenance and Lubrication Guide
Regular Inspection and Cleaning:
- It is advised to inspect the X/Y axis guideways bimonthly to ensure they remain clean, free from dust, dirt, and debris.
- For printers in frequent use, a monthly inspection and cleaning are recommended.
Preparations Before Lubrication:
- Before lubricating the X/Y/Z axis guideways, remove any dust, impurities, or plastic particles from the guideways.
Lubrication Steps:
- Use the appropriate lubricating oil and evenly apply it to the grooves of the X/Y/Z axis guideways (refer to specific diagrams for detailed operations).
- The procedure is as follows:
- For the Y-axis, move the print bed back and forth to ensure the lubricating oil is evenly spread across the guideways.
- For the X-axis, move the print head from side to side to ensure an even distribution of lubricating oil on the guideways.
Cleanup After Lubrication:
- After lubrication is complete, wipe away any excess oil from the guideway grooves with a soft cloth or tissue.
Precautions:
-
Use lubricating oil specifically designed for mechanical equipment to avoid using unsuitable lubricants.
-
Ensure that when applying lubricating oil, it does not come into contact with the printer’s non-metal parts to prevent damage.
-
Pay attention to safety during the operation to prevent lubricating oil from splashing onto your skin or eyes.

Regular Maintenance Guide for 3D Printer Fans
Purpose:
Regularly inspect the printer’s six fans to ensure there is no dust or debris accumulation, which is crucial for maintaining smooth fan operation and extending their service life.
Fans to Check:
- Hot end fan
- Model cooling turbine fan
- Breakout board fan
- Three bottom fans
Maintenance Steps:
- Power off the printer to ensure safe operation.
- Inspect the fans for any debris or dust accumulation.
- Clean with compressed air:
- Keep the fan blades in place.
- Use compressed air to blow away dust and debris from the fan blades.
Recommendations:
- We recommend cleaning the fans when the printer is powered off.
- When using compressed air, ensure you follow the correct method to avoid damaging the fan blades.
Precautions:
- Avoid using a damp cloth or liquid cleaning agents during the cleaning process, as moisture can damage electronic components.
- If there is stubborn dirt on the fan blades, consider using a soft brush to assist with the cleaning.
By following this guide, you can help ensure that your 3D printer’s fans remain in good working order, contributing to the overall reliability and performance of the machine.
3D Printer Extruder Internal Cleaning and Maintenance Guide
Regular Inspection and Cleaning Schedule:
- It is recommended to inspect and clean the extruder internals every two months to remove dust, impurities, or filament debris.
Cleaning Steps:
- Open the Extruder Cover, ensuring safe operation.
- Use Compressed Air:
- Use a can of compressed air to blow away debris or dust inside the extruder.
- Manually Remove Stubborn Debris:
- If there is debris that compressed air cannot remove, tweezers or other fine tools can be used for manual cleaning.
Precautions:
- Before cleaning, ensure that the printer is turned off and fully cooled to avoid electric shock or burns.
- When using compressed air, control the force to avoid damaging sensitive components inside the extruder.
- Be careful when manually cleaning, do not use brute force to avoid damaging internal parts of the extruder.
Post-Cleaning Inspection:
-
After cleaning, check whether there is any residual debris or impurities inside the extruder.
-
Ensure that all parts are correctly placed back in position and close the extruder cover.
By following this guide, you can maintain the performance and longevity of your 3D printer’s extruder assembly, ensuring smooth and consistent filament extrusion for high-quality prints.
