Regular maintenance of your 3D printer is essential. It brings two main benefits:
You can start with the items below.
You can use WD-40 Specialist Dry Lubricant, alternative lubricants are also acceptable.
This lubricant is designed to reduce friction and wear on various surfaces and will not attract dirt or dust.
Inspect and lubricate the Z-axis lead screw every three months. If the printer is used frequently, monthly lubrication is acceptable. Before lubrication, remove all dust and plastic debris first. Apply a thin layer of grease to the lead screw. Return the build plate to its home position, apply a thin coat of grease, then move the plate down. Add another thin layer of grease on the Z-axis lead screw. Move the plate up and down several times to spread the grease evenly. When finished, wipe away excess grease near the lead screw nut.
Regular cleaning: Keep the steel linear shafts clean and free of dust, dirt and debris. Wipe with a soft cloth or brush to remove accumulated particles. This prevents wear and ensures smooth movement.
Lubrication: Apply suitable lubricant to the steel linear shafts to reduce friction and wear. Choose lubricants made for linear motion applications (light oil such as 3-in-1 oil or sewing machine oil works).
Contamination prevention: Take precautions to protect steel linear shafts from moisture, dust, chemicals and other contaminants.
Three fans should be inspected regularly for dust and debris buildup.
Nozzle fan, part cooling turbo fan and circulation fan. Check them periodically to ensure smooth operation and long service life. With the printer powered off, we recommend compressed air. Hold the fan blades steady while blowing air to clear dust and debris.
Nozzles may fail after long-term use and need replacement. You can refer to the linked videos below for replacement guides.
High-temperature printing accelerates thermal grease depletion.
How to apply thermal grease:
Instructions
When replacing the nozzle, maintain the recommended temperature for the filament. Wear heat-resistant gloves to avoid burns.
