Hello! I'm using Rhino for designing my 3D prints, and Cura for slicing and MatterControl for printing, my printer is RoVa 3D, which has 5 nozzles. I have the latest (?) version of MatterControl 1.2.2, but it doesn't support multiple extrusion? I don't have the option in my MatterControl which allows me to assign multiple extruders for each part on the 3D print (as shown in the red box in the link below) https://www.matterhackers.com/news/mattercontrol-1-2-multi-extrusion-unleashed How can I get this feature? Or does my printer just not support it? Can I specify in Cura instead which part should be assigned to which extruder?
