We’ve recorded a quick video to demonstrate how to change the barrel on a Noztek Extruder. this is specifically geared for The Noztek Pro and Noztek Touch (including HT models)
Changing the barrel and cleaning the screw is really important to prevent barrel jam caused by the build up of material inside. This is essential when using viscose or exotic materials such as PEEK or ULTEM. It’s also a great regular habit to form in order to keep control of the quality of your extruded filament, and indeed the maintenence of your machine.
The video includes written instructions at each stage, to walk you through the process. We have demonstrated on a 2019 Noztek Pro.
Before you begin removing the barrel and screw, pleas emake sure all material is extruded. Please also allow enough time for the machine to cool down entirely before handling.
