Overview: Inside the Z-axis tower is a long-threaded metal rail called the Z-slide. This rail is attached to a motor and moves inside the printer. The Z-slide should be greased annually with white lithium grease. This keeps the Z-slide free of dust and debris and allows it to operate smoothly.
- Add a small amount of lithium grease to the tip of a clean Q-Tip.
- Apply the grease by moving the Q-Tip starting near the top of the Z-slide, moving down slowly.
