Filament not feeding

Hi all I just got my first 3D printer last week and I have been happily using it since but yesterday randomly the printer stopped feeding filament into the extruder? The gear that should be feeding the filament (the one under the little flap thing) just is not spinning at all. If I push it down it will work for maybe 5 minutes but then will stop working again. Does anyone know how to fix this?

Best Answer by rockytoptim:

I had this issue when I recieved my mini.  There is a little gear in the extruder that turns the gear that pulls the filament through the extruder.  This little gear has a grub screw that was loose and the gear moved so it wasn't meshing with the bigger gear.  See picture below.  The big gear and small gear should be at same level as shown.  Prusa has knowledge base for cleaning the extruder which show how to take the extruder apart.  There will be a extra step if the two gears aren't aligned.   In step 10 from link below there will be a couple of extra stps.  You will need to remove the two screws holding the stepper motor onto  orange block in step 10.  Once the motor is removed you will be able to adjust the small gear and tight the grub screw.
