How to Grease 3D Printer Z-Axis Lead Screws (PTFE vs Lithium)
3D Printing Glossary">Z-axis lead screws support the full weight of the X-gantry or build platform. Because they are mounted vertically, thin oils run down and drip off. High-viscosity PTFE or Lithium grease clings to the thread grooves, ensuring smooth, silent micro-stepping.
Step-by-Step Procedure
1. Wipe Off Old Dirty Grease
Use a clean rag or paper towel to wipe away old, blackened grease and metal filings from the entire length of the vertical threaded rod.
2. Apply Fresh Grease
Apply a continuous thin bead of PTFE or Lithium grease along the middle and lower working section of the 3D Printing Glossary">lead screw.
3. Cycle Z Axis from Top to Bottom
Power on the machine and use the control screen to jog the Z axis through its full vertical height 2-3 times to spread grease into the brass nut.
