Comment on Is this hot end salvageable?

  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

    @brillotti @Starfarer yeah for most PLA in general I would recommend+245•C & then brief off the material look up #3DPrinting brush #tool

    Made a lot of progress but it is in the screwheads the attach the hot end. Ridiculous

      If push comes to shove, you can heat up a screwdriver tip with the lighter, and use that to melt some of the PLA in the screw head enough to unscrew it.

  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.

    There’s a massive blob stuck round the thermistor wires that is detached from the hot end. Tried to melt the blob but cant get the middle to heat up.

    If the wires do get broken are they easy to replace ?

      Can’t say how easy or difficult it is to replace the thermistor. Haven’t had the pleasure.

      I don’t know how big “massive” is, but its effects could range from negligible to throwing off vibration compensation/input shaping or worst case being massive enough to cause excessive motion and having the inertia rip the wires apart over time.

  I’d get a new one at £30
