I came across this "Ultimaker 2 UM2 dual extrusion kit" today, but it appears to simply be the current design with an extruder nozzle/hot end mounted into the factory prepped space. Here's the link: http://www.dhgate.com/store/product/3-d-printer-parts-ultimaker-2-um2-dual-extrusion/216552327.html It doesn't appear to address the nozzle-lifting issue, nor perhaps any of the other issues that Team Ultimaker have run into during their R&D. Does anyone out there know anything about this unit, and if it works?? If it does "work", does Cura even support dual extrusion?? Thanks for any info regarding this...
