Have you adjusted your extruder acceleration and checked the extrusion esteps yet? I was having major problems because my extruder motor was loosing steps when it tried to return the retraction distance. Reducing the extruder accel and making sure it extrudes 10mm when it is instructed to GREATLY improved my print quality.
Check here for info:
I recently got a Taz 2, and I’m having a wonderful time with it. Most things I print are coming out great, but there’s one small issue that I’m hoping someone can with me with. The issue is with small models with lots of rapid retractions; the filament seems to slip further and further until it eventually backs all the way out of the print head. Here’s a prefect example of one that does it:

The base prints great, but the pins don’t print at all. After the first layer or two of …
Frakk:
“A-retract” is the actual setting you need to lower to ~900, that’s what I have it set at.
“A-max e” in the safety acceleration limit, this value I would set to 1000-1100, anything above that will be too fast.
“e-steps /mm” I also re-calibrated to ~920, giving me proper filament travel. Extrude 10-30mm from pronterface and see how much you are actually pulling in. This shouldn’t matter for the problems you experience but you’re prints will come out denser/looser if it is not right.
After you’re done changing, you have an option to make it stick after power cycles with Save, or Load, and to reset factory defaults.
Orias: Slowing down the extruder slowed down the print a little bit since these movements take a fraction of a second longer, depending on the print they add up. It made no difference with arcs and X/Y movements, but I adjusted the same settings for XYZ and found significant speed. Between Slic3r profile and hardware changes I saved 10hrs+ in a ~20hr print.
