After about 50 hours of build time, you should lubricate the threaded rod on your Z-axis and
the X-axis idler pulley. To lubricate the threaded rod and the idler pulley:
1. Find the tube of PTFE-based grease
included with your Replicator 2.
2. Grab both sides of the build platform
and push it gently to the bottom of the
MakerBot Replicator 2.
3. Use a clean, lint-free rag [or your finger]
to spread the PTFE-based grease onto the
top section of the threaded rod.
4. Make sure you get the grease inside of
the threads themselves.
