5. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your Anet ET5 3D printer. Perform the following checks periodically:

• Clean the Print Bed: After each print, ensure the print bed is clean and free of debris or filament residue. Use isopropyl alcohol for thorough cleaning.
• Lubricate Moving Parts: Periodically apply a small amount of lubricant to the Z-axis lead screws and Y-axis guideways to ensure smooth movement.
• Check Belts and Pulleys: Ensure that all belts are properly tensioned and that pulleys are free from obstructions.
• Clean the Nozzle: If you notice print quality degradation, the nozzle may be partially clogged. Refer to online resources or the manufacturer's guide for proper cleaning procedures.
• Inspect Electrical Connections: Regularly check all electrical connections to ensure they are secure and free from wear.
