Lubricating the Threaded Rod and the X-Axis Idler Pulley
4. Make sure you get the grease inside the threads themselves.
5. Grasp both sides of the build platform and move it to the top of the MakerBot Replicator 2X.
6. Use a clean, lint-free rag [or your finger] to spread the PTFE-based grease onto the bottom
section of the threaded rod. Make sure you get the grease inside the threads themselves.
7. Locate the X-axis idler pulley. If you are facing the front of the MakerBot Replicator 2X,
the idler pulley is at the top left side. The idler pulley is one of the pulleys that allow the rubber
belt to move the extruder from left to right, or along the X-axis. The pulley at the other side of
the gantry is called the timing pulley and does not require lubrication.
8. Squeeze a small amount of the PTFE-
based grease directly onto the exposed
area of the dowel inside the idler pulley
and manually move the pulley back and
forth to spread the grease.
