Rondavouz,

Is that print with or without the fan mod?

This was after leveling bed and extruder feed length. Shouldnt be any big problems with overhangs on the model.

printed in ABS at 195.
For me it looks like you are extruding way to much plastic.

Side note - holy smokes Repetier is 100x better than Prointerface. I thought Prointerface was fine for my purposes, but finally made the jump. So glad I did.

EDIT: I did have a case on this time, and did not before. Maybe that's the difference.

Finally, you can increase the nozzle diameter to something like .37.  Really, the fan is the first step.  The angles you can accomplish with the overhang are really impressive when you get there.

Where should I start on dialing this in?

I just upgraded/replaced:
Print carriage
Z-axis threaded rod
Hotend
