Lubricating the Threaded Rod and the X-Axis Idler Pulley | Continued
7. Locate the X-axis idler pulley. If you are
facing the front of the MakerBot Replicator 2,
the idler pulley is at the top le side. The idler
pulley is one of the pulleys that allow the
rubber belt to move the extruder from le 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.
