Hobbed bolt problems

I am almost ready To start my first print. The only problem is that the plastic won't come out of the extruder. Everything is heating up properly, but nothing is being extruded. I am fairly sure It is tight enough to extrude ( not too tight though). I was wondering if there could be a problem with the hobbed bolt?
Thanks

What machine (and extruder) do you have ?

Have you tried turning on the heater, set to the correct temperature, and manually pushing filament down into the hot end (you will need to release the filament gripping mechanism)?

I have a mendelmax 1.5 and a budaschnozzle 2.0. I have been able to push it down manually, so I know there is no jamming of the plastic.

I'd bet that you don't have the bolts that tension your extruder tight enough. They need to be mighty tight on the extruders I've seen.

Are you talking about the screws that have a spring over it to add to the pressure because i have screwed that in pretty tight.

Do you have the Wades Extruder? You could try tightening those screws. I would also try taking the hobbed bolt out and seeing how clean it is. Could you also post a few pictures of the hobbed bolt, Extruder etc.
