Hi! I've had an unfortunate incident with my UM3. The filament didn't stick to plate and instead started gathering around the nozzle. Eventually it crept up into the print head itself and now basically the area inside the print head, in and around the print cores, is filled with solid PLA.
I'm trying my best to get it out but I'm guessing I'll have to try and replace the print head after I've gotten it all out. I can't really imagine that this hasn't affected it printer in some inreversable way.
Has anyone else had this happen to them? Is it possible to buy a replacement print head? I can on
