So you've let your printer run over night, and you hurriedly rush to your printer to see what amazingness it has printed...but instead of a print, you find a massive blob affixed to the end of your extruder. OH NO!
What's likely happened is during the print, the print became detached and stuck to the nice and hot hot end. The extruder kept extruding and the blob grew and grew, leaving you with the fun surprise you find before you now.
Relax, keep calm, it's not as bad as it seems. There are a couple things you can do to fix this issue.
First, you need to keep in mind what can be entangled in the mass/blob that has formed around the hot end, which are the leads for the thermistor and heater cartridge. The leads for the thermistor are the ones to be most careful with as they as thin gauged wires.
We now want to preheat just the nozzle. Depending on the material you are using, it will require a different temp. In any case though, you want to be significantly hotter than your print temperatures. For example, if the blob is made of:
Once the hot end is up to the set temp, using a pair of pliers, carefully work the newly molten areas of the blob free. Again, be very cautious around the leads coming from the hot end, in particular the thermistor leads.
Work slowly and cautiously around the mass, no need to rush it. Doing so will likely result in having to purchase replacement parts.
