Introduction

This page describes the K extruder for RepRap Mendel.

This extruder is designed to work with a supply of 3mm diameter plastic feedstock. If you want to use 1.75mm diameter plastic, see this extruder instead.

The K Extruder is based on Minimalistic Mk7 replacement.

I wanted to design a single extruder driver that could

  1. Be bolted to the X carriage of Mendel and run as a normal extruder,
  2. Be mounted with J Head Nozzle, and
  3. it is easy to assembly.

Features

  1. a small filament driver means that the motor runs on low current;
  2. we use screw tap to make the filament driver;
  3. Do not need gears;
  4. Uses the 623 bearing
  5. Designed to work at higher extrude speeds than the old Mendel extruder, giving shorter build times.
  6. The back is open to make it easy to clean the teeth of the drive gear.
