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.

Just go to the Advanced tab and change the tool change retraction distance. That determines how much is retracted at each tool change.

That doesn't help. The problem is that the nozzle doesn't lift during the retraction even though I have set the zhop to .5. Granted that my object has quite a few shells. I need to be able to tell the damn thing to lift vertically about 5mm or so during a filament change.

If you want to add Z-lift to the tool change, then you can probably do that in the tool change script really easily.

Something like this:
G92 E0
G1 E-10 F800 ; tool change retract
G91
G1 Z2 F1800 ; Z-lift
T[new_tool] ; switch to new tool
; do whatever else you need here after the tool change
G1 Z-2 F1800 ; Z-lower
G90
G92 E0
G1 E10 F800 ; tool change prime
