Description
The D.E.I.S.S. extruder provides a dual extruder with only one stepper motor by the help of an RC servo. This makes it possible to realize a dual direct drive extruder which is lightweight and space efficient, it's only slightly bigger than a wade extruder. Because it is a direct driven extruder with PTFE tube, it is possible to use flexible filament as well as PLA or ABS.
The extruder was designed for the Robo3D printer, but could be adapted to many printers by adapting the x-carriage. This guide will describe how to assemble the DEISS and how to integrate it to a printer at the example of the Robo3D.
An adaption of the firmware is required to drive the extruder, since this concept is new, it is not prepared in Marlin firmware, the changes are documented in this guide.

Features
• Direct drive dual extrusion
• Body fully printable
• Compact setup, comparable to stock wade extruder
• Low mass due to single motor setup
• Nozzle level mechanism
• Quick extruder change setup
• Supports flexible filament
Thanks to Ziggy from Robo3D forum, he helped me at the firmware adaption.
