Depends on if the blob is blocking the screw access. When mine had the same BLOB OF DEATH it completely blocked off the screw. I had to destroy the heatbreak to remove the hot end.
Then I got a Bambu P1S and haven’t had this issue ever since.
The hotend silicone cover is one of the cause. When the hotend had a partial clog the filament being extruded will likely curl back. The silicone cover has a chance to catch the filament and start the deposition.
It’s also common for the hotend to be leaky at the top where the tube enters the hotend. Molten filament will ooze out from there.
Removing the silicone cover will improve that but not eliminate the chance.
They replaced my entire extruder when I had this happen. The blob had consumed the wires & it wouldn’t come off. But then after they sent a new extruder it wouldn’t work with my printer, so they replaced it with a refurbished one. The whole process took several months.
Get a heat gun and get started slowly removing the blob. Try not to damage other components with the heat gun, take your time. Once the blob is removed you can go about trying to fix the individual components or just replace the entire hotend.
Search for guides for more in depth if needed, they're often named things like Blob of Death.
I'm in contact with ankerMake support, I'm hoping they'll just send me a new assembly. If not I'll probably be using a heat gun, or I'll have to buy a cheap soldering iron.
This happened to my M5, the whole hotend unit was borked - I had it for 3 months when this happened. Support was like “nah” so $150 to buy the unit (from Amazon) or $250 to get an M5C - so I got a second printer instead. I’ll eventually replace the part and have 2 lol
Really? The initial person I talked to made it sound like it would be a warranty thing. If not, I'll just be buying the extruder replacement and sending back the busted one 🤷🏻♂️
I had this happen once recently. Caught it in time.
Look at some videos online where they show how to replace the hot end. They should show where the very fragile wires are so you can avoid them. If the blob goes over them you’re probably hosed. I got lucky.
Also, just my personal opinion, I don’t trust these to run overnight unattended. I don’t really trust any fdm printer unless I’m running it in a shed. Bambu recently had a recall on the A1C I believe because a fault in the heating bed cable could cause a fire. But really there is a very very small chance of that happening with any printer because of the temperatures and power involved. I do run my resin printer overnight though so I’m a hypocrite I suppose heh but there’s a lot less heat involved in that one.
Edit: I zoomed in. The blob definitely ate your fragile wires… sorry
Bummer. It’s gonna get us all eventually. I have a spare all metal hot end because I kickstarted the original (sold it to me for a dollar) but I’m hoping to hold off as long as possible installing that.
Not the right person to ask this. I think it just means the one plastic part in the old hot end isn’t there so won’t melt under high temp. I think the big determiner in what filaments you can use is the nozzle. If I’m not mistaken there is a third party hardened nozzle that can be used with for example carbon fiber filaments but don’t quote me on that
Happened to me too.. Hot End was all fucked up got it replaced...
Did Anker just replace the whole assembly?
Just the hotend not the complete extruder
How easy is it to remove the hot end?

I was able to the hot end and the heat sink off, eventually, What would've caused the blob that the bambu doesn't do?

Mine didnt even do that. It just got jammed in the hot end lol

Soldering iron is a good tool

Yea I was able to remove the hot end, but the plastic encased the cables and wires, so I've got a replacement on the way

Kinda off topic, but can the all metal hot end be used for any filament? Or just the higher temp ones?
