Walked away from a print this morning and came back to a blob being dragged all over the printer.
The blob of pla was in and around the hot end sleave and just everywhere.
Is this salvageable or do I need a replacement hot end?
Printer is a creality k1
How much time do you have?
DudeImMacGyver@kbin.earth 11 hours ago Probably, heat up the hot end and try carefully removing it.
You may be able to just heat up the hotend and remove the plastic with some tweezers, depending on how much of the extruder of covered.
How much does a new one cost? This is a PITA to fix, so I would prefer just getting a new one if its not too expensive.
Looks to be about £30 I think. Although looking at the service video I can’t actually get to the screws to remove the hot end because they are covered in pla
jsnfwlr@lemmy.ml 2 hours ago Get a new one and then try to salvage this one, and keep it as a hot spare - pun intended.
Soften the PLA with a lighter and then peel it off
Move the toolhead high off the build plate to give yourself room to work. Set the hot end temperature to somewhere in the filament’s melt range and let it soften a bit. Use needle nose pliers to gently pick away at blobs of filament, making sure not to damage any thermistor or heater core wires in the process. If you want to salvage that hot end, follow-up with a brass wire brush while it’s still hot, otherwise just remove enough goo to access the screws you mentioned.
I’d get a new one at £30
The pla has been pressed up into the casing. You need to clean that all carefully anyways. If you leave the hotend warm, it will peel off pretty easily. I have done that a couple of times. Something shabby and sharp and something for grabbing like small pliers should do it.
Thinks for the tips
If you do plan to replace it try the CHCB-OT hotend. Whichever one you end up getting remember to heat it up and screw the nozzle in while hot. I had them leak (between the nozzle and the rest of the hotend) if I didn’t do so.
I have saved one such hot end that had gotten plastic all over itself by heating it with a gas torch. The PLA burns off. Burned off the coloring on the aluminium too.
Next time I tried it, I melted the hot end.
Might have to save this as a last resort 😅

I’d start with removing the smurf jizz.
