Click the screen “Z-axis ⇡” . As the machine rises, the lead screw cleaning tools will also rise, capturing and carrying the black, thread-like sticky substance on the lead screws. Stop the upward movement when approaching the end of the lead screws to prevent collision between the tools and the auxiliary fan duct which could cause damage. Manually remove the cleaning tools from the top of the lead screws.

After cleaning, shake the WD-40 Specialist® Silicone well and spray it on the lead screws, ensuring the lubricant covers the entire length. Let it sit for about 5 minutes. During this time, reinstall the Z-axis lead screw cover. After installation, manually click the screen “Z-axis homing” and move the platform up and down to distribute the lubricant evenly.
