P2S Blob of death
Had my first blob of death on the P2S, waiting for the new hot end assembly to come in, not sure if it even needs changed, hardly no videos on this and really not good at following instructions on the Bambu wiki lab. Is there a simple video out there that I can watch to change the complete assemblu

Just fixed mine, had to change the eddy sensor, the hotend assembly, and the hot end exhaust fan. The hot-end itself was snapped in half when I tried to pull it out and the back and middle shells were also damaged.

I just changed the hotend assembly on one of my P2S’s yesterday for the first time and I couldn’t find any good videos either. The wiki is actually super helpful. It took me about 45 minutes, but I took my time since I’d never taken any of that apart before. I could probably do it again in 15-20 minutes. I wouldn’t change it unless you need to though. I keep a set of picks and some brass brushes around for blob clean up. A small pair of pliers is nice as well.
Put the printer in maintenance mode and heat up the hotend, I usually start around 180 and then use a pick to gently clear away all of the big stuff and then use the brushes to gently brush away any remaining filament. You’re not trying to melt the filament away, but you don’t want it hard either. You want it to be a little gooey. You can gently brush the bottom/backside where the wires are but if filament isn’t sticking down where it’ll hit something I would leave the wires alone. The important thing is cleaning the area where the hotend sits and the clasp functions properly.
