I'm working on printing 2 colors at the moment and there are lots of variables to play with for dual head printing. 1) I'm using Cura, does anyone have opinions on how good this is? Is Simplify 3D better at Dual Slicing? It generates an ooz shield and prime tower, but I still get plenty of ooz on the print. Are there better methods? 2) Should I use the dump bucket for priming on a Tool Switch? I setup some scripts to prime in the bucket, but it does take it's toll on print time. 3) What kind of retraction is best using the V6's for the off tool? Looking to reduce ooz. I'm using 2mm and may try 3mm. I'm afraid of going more and causing a jam in the heat break. I'll post some of my results when I get home, overall I think i have a good start.
