I ran a print last night and it caused a serious filament jam. The melted PLA ended up inside the extruder and is caked on the wires coming from the rear. I heated the extruder to 260 with the fans on to try to melt it out, but only the bottom most PLA melts out.

I've been really enjoying to 2+extended so far- this is the first issue. Do you think I should take the extruder apart? Any tips for removing the melted PLA? I can't use a torch because of the wires. Thanks!

    Warm it up so it's soft only around the block. So about 90deg and unscrew the fan shroud and try to remove the plastic. You may need to heat it more by it tends to come off more cleanly at lower temps.

    Once you get the blob off - realize your leak is most likely through the threads at the top of the olsson block. The problem is that you don't have a spring - you have the aluminum spacer - and it's not tight enough. So while nozzle is hot (150C is good temp) rotate the round steel coupler one turn clockwise looking from above. You don't need to take anything apart to do this. It might be already all the way down in which case be careful you don't break it (maybe move it CCW a little first to feel the force - brass is soft and easy to destroy). Rotate by sticking a thin screwdriver like tool into the holes of the steel coupler.

    If it is already all the way down then instead tighten the 4 thumb screws a little more. Again - while nozzle is hot (120C to 180C).

    I have the exact same problem. Please let me (and the community) know what you did to fix it. Thanks!IMG_8612.thumb.JPG.21ef1610d2657f5c34bf044290fab9a7.JPG

     

    Awesome. Thanks for the details everyone. I will try these methods.
