One point just occurred to me is the roll of filament near to the end that is to say very tightly wound round the reel. I had a problem with one roll that caused similar problems, it was initially solved by heating the filament in hot (below boiling) and straightening the filament. The reason this can be a problem is that it causes extra friction in the bowden tube and results in under extrusion.
The long term fix for me was to us a reel holder on the floor
to prove this is or is not the problem you could always cut a length of filament and try straightening it the see what results you get
hope this helps

Yep, like i said, the default settings are fine, and the only real settings you need to play with are temp and layer height and speed according to what type of filament you use. Also shell but (again only what in the basic settings) the other stuff is more complicated if you dont know what you are doing you are likely just making things worse.
Im glad temp solved it for you and can confirm raising the temp fixes these problems, especially for colorfabb. I had people telling me my printerwaas faultly when i printed at 50mm/s 0.2layer height at 230, but hey its what worked for me, and the tune button is great for experimenting on the fly.

Actually it didnt solve my problem, just improved a bit the overall quality, but there are some failures on skins yet, which I couldn't find out the reason yet... However, the infill is way better after the increase to 26% and slowing infill speed to 40mm/s.
