My hot end is hopelessly clogged with eSun 3mm PLA. When I tried to remove the filament it broke off at the entrance point so your online solutions won’t work. I’ve tried raising the temp and pushing it through with the pointed end of the metal rasp but it’s hopelessly stuck.This is the second time this has happened with this type of filament. The first time I luckily had an extra hot end so I replaced it. At that time, I had been having issues with filament sticking to the heated bed. When I replaced the hot end, I found that the funnel shaped piece on the larger fan was cracked and broken in several places. Since my other Mini has a flexy-struder head I was able to replace that piece. The quality of the print was very poor - something I’ve noticed with other Lulzbot 3D printed components. I can’t just reprint it because it has several screw sockets embedded in it.
In the meantime, I need to know how to remove this filament because I can’t afford to keep replacing the hot end and you’re out of them anyway. I had issues with the hot end on my first Mini and broke it trying to fix it. That’s how I ended up with the Flexy print head - it was all that was available and I have a small education business that relies on these printers! The lack of replacement parts is alarming and can put a small operator like me in real trouble.
So, we have several issues here. The most urgent is
The clogged hot end. I have several student prints that I need to get out by Tuesday and will have to pay for access somewhere else to print them.
I still need to replace the fan funnel piece for my now spare print head but am not sure how to proceed. I will have to buy yet another hot end for that print head, which I’m not happy about. These printers are both fairly new.
The clogged head is a recurring issue and the fact that I can’t replace the hot end implies that many others are having the same problem. It’s like buying a car and the steering wheel breaks and the car maker says ,“Sorry, we’re out of replacement steering wheels.”
The machine is under warranty. How can you help me with this clogged hot end asap.
