I made this test to check whether I got good filament tips and if there are any problems with loading/unloading. Split it in Slic3r and assingn each part to a different extruder by doubleclicking the part.
I hope this helps!
If you got a filament that tends to string a lot, try temperatures like this:
1st layer 215°C
all other layers 195°C
Ramming parameters like in the last pic. My filament was OWL-filament.
