I have a flash forge creator pro with white PLA in the left extruder and black ABS in the right.
I'm trying to print a traffic cone using the simplify3d dual extrusion wizard but both times, part of the ooze shield / print fails and the pla nozzle gets jammed.
I can print the cone using a single extruder just fine.
Here are some time lapses to show you what is happening.

Any ideas?
