Ceramic Tape for the MakerBot Rep 2
You should replace the ceramic insulation tape on your MakerBot Replicator 2 approximately every 50 hours, if the white insulation has turned brown, or if it falls off of the heater block. We use pre-cut ceramic insulation tape to make the job easier. You can find some here, or purchase a six-pack to stock up!
As always, turn off and unplug your machine before doing any repair work.
