Last week my 3d printer suffered the dreaded "blob of death". I managed to resolve the problem, though left my printer slightly singed... And of course, Wolf has the same idea which I definitely don't recommend!

I had that happen to be a while ago, the clips an the hot end were so gunked up I just replaced the hot end entirely. The Nozzle that was on there at the time seems to be permanently clogged, not even bringing it to the maximum temperature and scouring it with a brass brush clears it. Fortunately I had a spare nozzle; I had bought a kit with a range of nozzles and a spare built plate (smooth, not textured like the Bambu ships with. I actually like the smooth plate better.)
Fair warning, the A1 series is NOT designed for easy teardown, there's a specific order parts need to be added/removed, and it is NOT easy to intuit from visual examination. I actually left the back panel (the 'beauty plate' off my A1 mini just in case I need to do more work, so now I can see the extruder control circuit board all the time.
Ah, thass easy...
-Take a needle drill bit smaller in diameter than the nozzle opening
-Carefully drill into the plastic that has lodged into the hole, until the bit emerges from the back side
-Take a larger diameter bit, and carefully drill into the feed side of the nozzle
-Take a standard pin, and push the loosened mass back through the nozzle
-Take a 25Lb Demolition Sledge to the Verdammt Thing!
-Breath out
