I really like this design, but I'm having an issue with it. It extrudes plastic perfectly until the plastic reaches the nozzle of the hot end. At this point, the extruder will just begin to grind at the filament. Sometimes I can push on the idler more and it moves about an inch, but then it refuses to go any further. Do you have any suggestions to fix this?
