Flashforge Dreamer (NX) - Replacing Printhead & Nozzle plus switching to a Silicone Sock - Part 4

I was having problems with extrusion again so took the nozzle out of the printhead to see what was going on with the heat-break tube.

About a month ago, I tried to replace the heat-break tube while the printhead was still hot and ended up stripping the threads on the nozzle & printhead. Big mistake!

The printhead is made of aluminum and the nozzle is nickel-plated brass. Aluminum will get soft when it gets hot.

Anyway, I needed to replace the printhead and the nozzle, so I decided to go ahead and try using a silicone sock for the insulation of printhead instead of the thin fiberglass (I assume) tape that surrounds the stock printhead, held on with Kapton tape.

Part 1 covers diagnosing the problem and removing the nozzle from the old printhead.'
Part 2 covers disassembling the printhead including removing the insulation, thermocouple, and heat rod.
Part 3 covers reassembling the printhead using Boron-Nitride thermal paste for better heat connectivity
Part 4 finishes the reassembly of the printhead, installing the silicone sock, and testing the printer.
