extruder extruding too slow

[tomh]

Hi there,

I have built a prusa i3 3d printer and I have been testing it. Every time I try to print the ground layer is good, but when the actual body of my piece is being printed
my extruder is extruding too slow. I can see the PLA is sometimes passing and sometimes not. When I manually force the filament the print is great.

This is what I tried so far:
raising the extruder temperature (up to 215°C)
replaced the driving gear

Can you guys give me suggestions to fix my problem?
