Multiple extrusion idea ( off-carriage multi-extruder )
Channel: Arthur Wolf
Date: 2014-02-23

This is a description of an idea of a system for multiple extrusion with low moving weight ( no moving stepper motor ) while maintaining the filament pushing gear close to the hotend.

This has already been done for single-extrusion : http://www.youtube.com/watch?v=4h8N3RZUSvQ ( you can get the history of the idea in the video ) , this is an extension to multiple extruders.

The hex-shaft-hobbed-gear was designed and made by our good friends at http://2engineers.com/
