I’ve been gettingI’ve been getting notifications for the last couple weeks stating that there’s filament on the nozzle and there’s not been any filament on the nozzle so yesterday I got the notification looked on my phone and didn’t see any buildup so I said okay let’s continue. When I got back to my desk at work I pulled it up and noticed that there was a blob, well when I got home this is what was waiting for me it took out the hot end fan ripped some other two wires which I’m not sure what they go to but I ordered a new tool head and hot end parts for

This has happened to me four times in the last 20 hours of printing. I’ve tried new 1st party hotends at 0.4 and 0.6mm, many different spools of PLA (Polymaker, Overture, and Bambu Lab). I also had to replace the heating block behind the hotend because I couldn’t excavate it from the giant mass of filament one time. Each time it has happened, it has popped off my toolhead front cover and sent my textured plate to the floor (along with the print). It seems to only happen when I’m printing Hueforge flat prints. Is there any fix to this?
EDIT: I should also state that I have never received any kind of error notification about this. It just continues until the print would normally be over. So if I don’t constantly watch the camera, I wouldn’t even know this is happening until it’s too late.
Wow, 4 times in 20h printing time is quite often. I’ve had my A1 for a month now with approx. 100h of printing time. So far no problems (knock on wood).
I’m wondering how this happens anyway. Where does the filament leak from and why does it accumulate in such a way? I had several 3D printers before the A1 (Anet A6, some Ender printer, a Kobra 2 and 3) but I never have seen this before. Is it a design flaw with the printhead and the hotends?
All of your questions are the same that I’m wondering. I really don’t know the answers though. I can say the problem didn’t start until about 1,300 hours of printing. And now it’s become very common. So something is wrong, but I don’t know what it could be.
I dont know why it started doing that either. I kept getting the notice that there was filament on nozzle but when I would check it was fine. So I was out of the house when I got it that day and looked at the camera and it was fine so I sent it. When I got back to the office i noticed the blob and shut it down. The new parts came in and it’s up and running again.

My only option when it happens is to heat up the nozzle to 300 and start slowly pulling blobs out. Wondering if some alignment item is messed up and keeps making this happen. I’m pretty new to this, and this is my only printer though.
I tried to do that but I noticed the hot end fan was broken off, and the thermistor wires were ripped out too.
