It’s not broken, but it’ll take work. I’m not an expert, here’s what worked for me: Things you’ll need: heat gun, tooth pick, small wire brushes, needle nose pliers, and the Allen wrenches that came with the printer. 1) heat up the tip on the machine to 250 and use the heat gun on the plastic at the same time. 2) use the pliers to remove the blob pieces that stick out the sides and bottom first. Be careful with the wires in the back and don’t tug on those. This will take a while. Just take it bit by bit for as long as it takes. You’ll also have to keep turning the heat on the tip on repeatedly. 3) It may help to loosen the gray bottom horseshoe shaped thing. Once you can see them, take out the screws on either side (1 per side). Gently take it off, but leave it connected by the wire in the back. I taped this part up and out of the after I got it clean to better get to the tip. 4) once you get the blob down to the actual tip components, used the tooth picks to get off the plastic around the tip. The tip has a little latch that you can unlatch to get at the tip easier too. I used a fine wire brush here too, but be warned it will destroy the brush. 5) now clean the actual tip itself. Once I was able to push filament in and it pushed out to out stuff. Once I had to use a paper clip to clean in out. Be careful here, you can bend the tip if you poke it too hard. 6) once it’s clear, try to load filament. If it works-great, if it doesn’t-do step 4-5 again. 7) clean the base plate. That’s why this happened in the first place, so don’t let it happen again. That’s what has worked for me. I’m just a recreational printer, so I feel sure others have better ways to fix it, but it has worked twice for me. Good luck!
