1) Is there any way to have a dual connector extruder that doesn't catch onto the Z axis lead screw? For now I've just rotated the entire extruder 90 degress, but I think that comes with the issue of too much of a bend in the bowden tubes in a couple spots. Or, is there a way to hook 3DChameleon up just a regular single connector? (but I imagine this way, feeding the filament back into the extruder, it would more than likely not line up with the tiny hole and not feed at all. This happens to me all the time when I try and do it myself, even with a diagonally-cut tip...)
2) So no go at all with Cura when it comes to 4 colors? I mean, we're given a Cura profile for the MK2 4 colors, but since Ultimaker printers only have at most 2 exturders, the purge tower plain-out doesn't form right with more than 2 colors. I searched quite a bit to find a solution to this, but unless there's a secret hidden plug-in that fixes this, I couldn't find anything other than Ultimaker employees saying "Sorry bro, we don't need more than 2 colors, so deal". I've always used and liked Cura, and I've been trying to use Prusa instead, but the interface is....soggy garbage compared to Cura. It's tempting to just model my own purge towers and use Cura, but that's obviously extra work.
3) Finally, where exactly do you feed the lines up to when loading up all 4 filaments into the MK2 before the print? Do you put them just past the gears inside the initial 4-way motor, or up to the Y splitter? Can't find any clarification on this. And to add to that, do I need to make sure the MK2 is set to tool 0 before I start a print, or is that handled through the g-code automatically before each print?
