Fourth try on a print. Tried to add some adhesive to the bed to get it to stick better. Watched the first two layers and went to bed. Woke up to a printer on strike.
Oof, that's a bad day. Hope the cleanup wasn't terrible.

It's a learning experience. Is your nozzle torqued to spec? Only time I've seen something like this is when the heatbreak/nozzle weren't set correctly on a v6 hotend, and even then it just oozed down, didn't consume the entire heatsink. I kept that in my box of learning lol, swapped everything to hotends that are secured so they don't spin freely after that, was petg so it degraded in the heat and was such a pain in the ass to remove from set screws, was ok writing it off.
Bed adhesion is often caused by surface cleanliness in my experience, some setting will influence it but you're going to chase problems if your surface has residual oils, some surfaces are more sensitive to it but even the oils in your fingerprints can cause a loss of adhesion. Light dish soap and water is the general recommendation for a degreaser but be aware that this will damage some surfaces, I've got some that explicitly want only 99% IPA and another that only wants a clean microfibre cloth.
Drafts can cause an issue too, seen some abs fail becauae I didn't have the enclosure latched properly and the doors worked their way open with vibrations from printing, I keep mine in my garage and live in Canada, enclosures are a must for me.
I had that happen once. it just bout pushed the fan off the head since the clips are broken but it fits good enough™️
OH NO
I don't see a beginning of a print anywhere, did it not even manage to do the first layer?
If that's the case, a word of advice to always be present for the first 2 layers of your prints, at least for the longer ones.
I didn't take the photo immediately - tried cleaning a bit before it occurred to me to document it.
I've a massive blob like this one time when the nozzle got clogged and the extruder created enough pressure to push the filament through the threads of the hotend block. It was on an Anet A8 and I ripped a lead off the thermistor trying to get the plastic off so I ended up replacing the entire hotend.
You can try to heat up the hotend to a fair bit under the melting point of the filament to where it's soft and somewhat pliable but not runny or sticky and then trying to peel it off. Though you'd risk damaging any leads to the thermistor, heater, or your hands if you're not careful.
Good luck on fixing the printer and getting back to printing again. 3D printing is a really time consuming hobby
Thanks. I am really frustrated with myself for letting this happen. Pulled everything apart and recovered most of everything, but managed to damage the clip that holds the extruder in place, so now I get to learn how to do surgery and replace the entire assembly. I wish I had gotten a bit more time before having to do a major repair...
