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. A large motor with high torque, 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.
