The part to be printed came loose, and the AI did not recognize it. The filament formed a very large blob. How can this be removed without causing any damage? Can I slowly heat the filament with a hot air gun? It is PLA.
Does the hotend still work? or did the wires break? If so, heat the hotend up and the plastic will soften, so you can work it off. This is the easiest way, because its heating it from the center of the blob. This will give you the best chance of saving everything. No need to heat it any hotter than its melting temp. Be careful of finger burns
