I’ve downloaded the newest Cura for Lulzbot and have begun “moving in” to the new program by setting up my various print heads (Taz 6) and playing with the new controls.
To cut to the chase, I have added and set up the Dual Extruder V2, opened two separate parts (of a two color print) on the build platform, and have been thus far unable to “Dual Extrusion Merge” the two in the same way that I used to in a previous version of Cura. There are three options at the bottom of the menu that appears upon right-clicking the second object (with 1st object already selected): Group Models, Merge Models, Ungroup Models. All three are"grayed" out, and cannot be clicked. I have not found a dual extrusion merge option anywhere else. I have been able to assign each model with it’s own print head, however.
P.S.: I’ve crashed the new Cura 4 times in the past hour! I don’t think I’m pushing it too hard
