¶ Maintenance Necessity
- Anti-rust and Noise Reduction: All-metal idler structure is susceptible to friction noise and rust. Regular lubrication can extend equipment life and ensure printing accuracy.
- Factory Pre-maintenance: All equipment undergo basic lubrication treatment before leaving the factory.
¶ Maintenance Cycle Recommendation
Frequent use: Once per week
Infrequent use: Once every two weeks
¶ Note
K2 Plus maintenance recommendation can be referenced in this Wiki Page: K2 Plus Periodic Maintenance Tips
Abnormal Response: If metal friction noise occurs during equipment operation, stop immediately for maintenance.
¶ Filament Specification
¶ Recommended Lubricant
WD-40 Specialist® Silicone（Must verify authentic anti-counterfeiting mark, suitable for belts without causing damage）
Prohibition Notice: Use of non-certified lubricants is strictly prohibited as they may cause bearing corrosion/steel shaft wear/seal aging and other failures

¶ Standardized Operating Procedure
¶ Required Tools
Lint-free cloth
WD-40 Specialist® Silicone
¶ Steps
Use a clean lint-free cloth to wipe dust and debris from the idler wheels on the left X-axis assembly (2102013343) and right X-axis assembly (2102013346). Do not use paper towels that may leave fibers

First clean the X-axis guide rail with a lint-free cloth, then spray "WD-40 Specialist® Silicone" along the entire guide rail. Follow the steps in the Wiki article: K2 Plus X-axis Guide Rail Cleaning Guide
After long-term use, Y-axis lead screws may accumulate black, thread-like sticky substances. Use a lead screw cleaning tool (recommended to print with PETG filament) to clamp both sides of the lead screw and perform a homing operation to clean it.
