What is so catastrophic? Looks fine.
I had a catastrophic failure. Runaway heater led to the aluminum getting so hot that the nozzle dug into the metal build plate from expansion and then the metal got so soft the nozzle ripped out of the heat block, then that caused the e axis to melt. Trashed the entire E axis in terms of plastic parts, heater, heater block, thermistor, heat break, nozzle, print fan, heat break fan, heat sink, and build plate. |

The nozzle came loose? It happens once in a while .
Remove, break off all the bits that don't stress other stuff on the hot end, warm until the plastic is soft, and clean off. |

Literally is in the fan blades. |

The one time that happened with my old Monoprice printer, it was easier to replace the entire hotend than to try to save it.

I have to laugh a little bit. Those of us that have that have been around since the beginnings have gone through the same shit.
Heat gun very sparingly and small needle nose to get the bulk out. Might have to blip the heaters for the hot end on to about 60% of extrusion temps. Replace the nozzle and move on. If I am on the PC later I will post some pics to make you feel better. |

After the guys in the office shoved raw filament into the fans changing materials hot I bought a 12 pack and terminated them for plug and play replacement. Outside of the drives there isn't much to the hot ends. |

Oh, I've seen worse. This thing was working so well too. Like Mr Consistent. I know I can clean it up, and should, but it'll give me a good reason to down convert the SR to stock. Just swap out the effector and move on. I will try to clean it up, but in my industry, this is what we call "spare parts".
