Prusa I3 Pro B fails

[Bernd]

you can not put pressure on the filament and it can thus also not be pushed by the gear

[William]

yes you are right i can push the filament without the wheel rotate ! Although, if I do this with the engine built state rotates the gear from the motor but the filament remains on the spot.

That is to say,the gear doesn't drive the filament to the nozzle at all when extruder motor runs ?am i right ?And their gap is like the pic i posted on your extruder? If i'm right,i believe you can adjust the gap between the two wheels and the filament.

[Bernd]

Yes you are right ! But how can I adjust the gap? I have not seen to adjust anything

[Bernd]

maby the wheel have a wrong size ? or the gear ?

Eh,i think its the spring.I dont know if your spring had some mistakes,cuz the gap will change once you press the handle,isn't it?

[Bernd]

when I press it, the gap is larger that's right, but I can not push it upwards'm afraid that I the lever terminating
