    Hey everybody,

    I'm a student organization that built a Prusa i3 printer and we are having some issues with it. When I extrude to test if the right amount of filament is coming out it works great. But after I have done that and go to print something the filament begins to strip.

    I make sure to clean out the hobbed bolt before I do both of these things. The problem still persists even after I have taken all the grinned up filament out of the bolt.

    I change the amount of tension on the filament and no matter what it still ends up striping the filament.

    Is there any solution to my problem?

    I'm sorry, but what does it mean 'the filament begins to strip'? How does the 'stripping' looks like?

    The filament gets stuck in one spot, and the hobbed bolt begins to grind away at the filament. I should have used the word grind, instead of stripping. It leaves a little Cresent in the filament that has been grinder away.

    Oh, I see. Yes, that makes sense.

    What filament are you using? maybe your hobbed bolt is bad? Did you try with another one? What is your extruder type? Can you take pictures of your setup (spool holder included)?
