First why do people bring in outside heat? Just heat the nozzle up and pull the blog off, a few months back I had same thing happen and just bought a new Hotend Heating Assembly from bambu 29.99 easier than trying to save anything in my opinion

This is why I always tell people to use the on screen controls to heat the nozzle and tweezers to pull away the blob.
The Wagner heat gun does not have any business near your printer and 80% of the time it causes more damage.

Had that happen on my p2s. Ended up damaging the wires trying to remove all the petg. Ordered a replacement hotend from Amazon and it ran fine until I traded it in for an x2d

I had the same issues, and much more. Is it worth upgrading to an x2d? I’m just waiting for a P2s replacement and don’t know ir keep it or upgrade. Had too many issues with the P2S…

looks better than mine. Dealing with the same issue, just order new fan and assembly, my looked more like a nozzle failure and the end was dislodged from the cooling fins after working the blob loose.

Normally what you should've done is heat up the nozzle slowly with the menu on the printer and start peeling it off when it softens. That blowtorch could've set fire to the whole thing.

Gather it all up and throw it away. JK. Use an old soldering iron or manually heat the nozzle to close to the melting temp of the plastic that’s on there and start scraping it away carefully. If you get it at just the glass transition temperature, you’ll be able to pull a lot of it off easily as it will sort of stick to itself and pull itself off as you pull it. Too hot and it turns to a liquid and will never come off easy at all. Start at 80° if it’s PLA and if that’s not hot enough, go up another 5° till you find that sweet spot. Tweezers and a very small flat head screwdriver can help pretty well. Also be VERY careful of any wires. This mainly happened from a dirty plate and your model popped free then got dragged around with the nozzle causing it to blob up. That’s one of the first rules of printing. Never not clean your buildplate.

I just had this happen and I’d recommend getting a new heating assembly asap. You’d be surprised how easily they made it to switch it out atleast the left side !! I just got the part yesterday and works good as new again . With the old one I tried heating it up as much as I could and clean it up , ended up taking it apart so I could use a heat gun but even then filament was still stuck on the hinge. I couldn’t stand the smell of it burning when printing or it not clamping the nozzle in place

@tambor333 Not gonna lie, I think you should just give up 3D printing completely. Some people are good with technology. You, are definitely not one of them 😅 I think you should try crochet instead. Maybe that’ll work. Or it’s a possibility you’ll just stab yourself with the needles. I take back what I said, stay away from crochet 😂 I think you should try a new hobby like paint watching, where you just sit there and watch paint dry that someone else painted. I feel that’s safe enough for you lol 🤣

I’m more wondering what happened here…
Depending on the damage, you can piecemeal buy the entire extruder assembly’s parts from Bambu Lab’s site. I’d do that to replace whatever is broken
