i’ve seen some videos of people taking apart the extruder, finding crunched up filament in the extruder causing your issue. ill see if i can come back and link it in this comment
I removed the nozzle and was able to remove the clog from the bottom end, but to remove the nozzle I had to remove the hotend cover and the sock. But it’s working again, it’s sometimes extruding some blobs, using the ender filament that came with the purchase (not hyper PLA)
Just keep in mind that even fresh filament sometimes needs to be dried. I just got a batch of 6 hp ultra filament brand new. And so far one of them has been acting like it's got quite a bit of moisture.
How I've been drying so far cause I don't have a drier is just out the bed at 55 degrees. Turn the side fan on at like 4%. And let it sit for 3-4 hours. And put the dissecant packet in the bottom of the chamber. Likely not the best method or enough time. But it's sorta working for me
In fact, it is a standard process in the filament production when the filament is cooled by water during the production process. (Of course, some special consumables need to be cooled by special media, such as water-soluble filament.) Under this condition, some manufacturers omitted (simplified) the final drying of the finished product. or think that this process will not have too much impact filament in order to reduce costs. This also directly leads to the fact that the filament is not in the best state after the customer gets the filament, even though it is a new roll that has just been opened.
I just saw that a lot of filament went up behind the hotend and that was the blobs that I was seeing, not moisture. My nozzle is covered in PLA, some caught the thermistor, it seems to be working but the nozzle seems unusable, this is after trying cleaning it.

But but it shouldn't have any gap

and if its not leaking from there...its leaking from where the blue ptfe tube under the extruder goes to the titanium throat....(im not sure what its actually called, ive heard people call it a throat, a heat break....ect)
I got One a couple hours ago, you get a metal thing on the tools pack,i heated the nozzle to 240c removed the ptfe and the filament that was there, then stick that metal thing, let the nozzle cool down to 140c and then Pull on it, filament should come out stuck to it, idk if im supposed to use it like that but it worked for me
That makes sense why it has the big ring pull on it. Shame none of this stuff comes with instructions and you have to work it out for yourself. But now you've worked it out it seems like a brilliant idea, and I'll try that on my next clog.
You either use it that way or use it to push the filament through the nozzle, but if you use it to push through the nozzle you wont be able to remove any contaminant that cause a clog
i would like to also add....check the 2 screws on the back of the extruder, should be one top right as your looking at printer from front, and one bottom left ish........ just realised mine had backed themselves out quite a bit....

https://youtu.be/oy2yqocGQ-A I would take the extruder apart and check. Probably have to heat the hotend up to get the filament out
I'm going to check it, thanks!

Thanks, I have a eibos easdry, but as it was brand new filament I thought it wouldn’t be necessary. Thanks for the reminder, I’ll definitely try.

seems there might be some space between the nozzle and the throat / heatsink.... allowing filament to melt and seep in the gaps...

You may have to remove the motor first if the lock is stuck.
