				Prusa I3 Pro B fails

				Hi, I have a Prusa bought I3 Pro B on Ebay by Greetech, unfortunately I have so problems. First, I get no filament from the extruder, I checked everything and the motor rotates also correct the allen screws on the wheel I tightened. Unfortunately I do not screw to the extruder that I can increase the pressure on the filament. It looks as if the pressure is insufficient to the filament continues to transport. Second, the threaded rods and the normal bars are so crooked that they become wedged at work in the upper brackets and everything stops. So can not print it. The quality of these are really not good. Can I get compensation for it please.

				I thank you for this link, but most I have already tried and has not helped, it looks as if the pressure is insufficient to the filament so as to continue to carry and unfortunately I have with my extruder not screw up to to increase the pressure.

If everything is OK,it shouldn't be like this.And have you already checked your extruder carefully?Cuz i think the filament doesn't require that much pressure.Like the filament must stay in the groove of the driven wheel.Like the pic below shows:

In addition,its my opinion that if you wanna increase the pressure,you should have this one screw up,shouldn't it?

				No, sorry it doesn´t works ! I have try everything... but i think the pressure for the filament is to low. When i push the filament with my hand down the fila comes out of the nozzle.
