DXU - Dual Extrusion Upgrade for UM2+
youmagine
FEATURE This project upgrades the Ultimaker 2+ to a reliable dual extrusion printer by building upon the great effort everyone put into Mark2 for Ultimaker 2 and Ultimaker 3. The print head holds two hot ends, originally designed for installation on standard UM2 heads for 1.75 filament. The right nozzle moves up and down, enabling easy nozzle swapping. This compact dual print head achieves a single extrusion print area of 220x223x205 and a dual extrusion print area of 202x223x200.

The firmware is modified based on the Mark2 version of Tinkergnome's firmware. CURA profiles are modified based on the Mark2 profiles by tinkergnome and foehnsturm. The Mark2Tweaks plugin for CURA was used, developed by Krys Lawrence.
