I'm having problems with my Dual Extruder:
1) Doesn't retract filament in T1 before printing, leaving little blob wisps everywhere
2) Retracts over print leaving blobs/nozzle pox
3)Doesn't retract like Cura does between filament so that there's always wisps from inactive nozzle
Any help would be appreciated. I've attached my .fff file and some images I took of the print.
