prusa i3 pro b acrylic:

I've started having trouble with my extruder, it suddenly stops pushing down the filament during a print. So I think Im going to buy another one, unless anyone have any ideas that can solve the feeding issue?
If not what other models are working good?

ps the nozzle is not clogged or anything like that.

Have confirmed it's the nozzle issue?

I have checked everything I can think of. Raised the voltage to 1.1V..
Now it wont even extrude at all..
I'll probably try to clean it out and see what the problem is but right now I want to replace it with a better and more secure extruder.
