As far as I can see that last pic - you don't have a purge wall or purge column. This is the problem I've always had with simplify3d and dual extrusion. It just doesn't work.

Have you tried flashprint for this ?

I have been working all week with flashprint...like the program, but still no luck. no issues with adhesion to the bed. raft forms beautifully out of pla...then it all goes downhill from there. I have worked PVA temps from 190-215. Tried first layer speed all the way down to 10 mm/s.
Tried both tree and linear supports.
tried purge tower, wall, both together.

Definitely at wits end...
any further thoughts on your part would be appreciated!
