In depth look at whats available for extruders, build types and installs.
lots of information and research to help guide you through the buy or build
process. The forum is building a hi-temp 3d printer that utilizes a pellet extruder built from plans and acquired parts.
This info from mahor design

The extruder from high temp is different, it has a different screw and barrel so this info is for referance only to establish a working setup, once established I will post
