We are using a Prusa Mendel with a .3 mm tip at 15mm/s for perimeter lays and 20mm/s for the infill.
Basically, when things work, we get kid of good prints, but typically it just messes up within the first few layers and we get trash.
I've attached pictures. I've tried lowering the speed, increasing the temperature, increasing the pressure of the extruder.
