Filament Maker TWO nozzle cover change

This is an easy maintenance procedure for when the current nozzle cover is worn out or damaged in any way. Follow the instructions below.

Overview

The nozzle cover (small circular disk) rests below the nozzle and is held in place by the nozzle plate (large black metallic panel). 

It is particularly important to avoid backflow, preventing any damage to the inside of the extrusion system. It also functions as added insulation.
