Extruder Clicking - Drive Gears Binding - Simple Pro

User Comment: I tried to load and unload the filament but with no success. It seems something about the mechanism that is supposed to pull the filament is broken.

*See a video here.

 

PB Response: In my experience, this is caused by the screw that holds extruder arm being too tight. Use your 2.5mm hex wrench to loosen the screw just slightly. I think you will find that the drive gears will spin more freely.

Hope that is helpful,

    In my experience, getting filament into the actual extruder nozzle involved bending the tip of the filament in various directions until the gears actually guided it into place.

    The gears themselves bend the filament a little bit, and don't always guide it right into the nozzle.

    The issue I'm having is that the extruder is clicking, not extruding during the print process, and I'm missing entire layers of a print. I don't see how this is possible, because the "Load Filament" process allows you to just keep pulling a constant string of filament from the nozzle, which works fine on my printer.

    So my Printrbot Pro is also experiencing this grinding while extruding... 

     

    I've attempted:

    * loosening & tightening the black machine screw from PB response

    * lubricating the freely rotating gear 

    * loosening and tightening the "other" screw on the back side of the Extruder Arm assembly

    Also, even printing at slower speeds, I even tried printrbot cloud settings the issue still exists...

     

    Lastly, even when loading filament, via the Pros' touchscreen, extruder continues clicking randomly, leaving me to believe that it will happen during printing, which it does

    Sorry to hear of the trouble Aaron.  Looks like you are going through appropriate troubleshooting steps.  You may consider swapping your nozzle.  

    Also, measure the diameter of your filament to make sure that it is, in fact, 1.75mm wide.

    I hope that is helpful,
