See that small blower fan that blows onto the hexagonal fins above the hot end? Make sure that things spins when the printer is on. If not, clean it...For a while now my print head has been jamming/clogging. Loading the filament will go just fine. Once I start a print it almost immediately jams and the hobbed bolt just grinds into the filament. I used a bunch of inland cleaning filament today to clean out the nozzle (heat it, let it sit, cool it, cold pull) and while it did get a bunch of crap out, it didn't fix it. I'm using Inland 3mm PLA. I've tried various temperatures in the range on the label (205 - 225 C). Nothing on my print head looks broken so I'm totally lost.
