Guys, I'm almost giving up here...

Extruder and nozzle are NOT clogged at all, I cleaned until I could see through both. Yet, very, very thin filament (sometimes none) is coming out. I'm loding a ton of prints...

Things I've tried:
- Clean nozzle
- Clean extruder
- Leave the heat on for 30 minutes before cleaning it again
- Changing filament (PLA various colours, one ABS)
- Tighten the spring of the filament holder
- More temperature

Any other ideas os things I might be missing? I really gets on my nerve when I leave the printer and the filament gets stuck half-way done and I lose a lot of printing hours...

Is it possible that you don't have enough motor current going to your extruder stepper? That would make it hard to actually push any plastic out that tiny hole.

Do you actually see the extruder motor spinning and driving filament in? Or is the drive shaft slipping (i.e. it's spinning but no filament is going in)
