help with clogged Mk4 hotend?
(sh.itjust.works)
Total clog with prusament pla in line. Can't feed anything through even at high heat. Cold pull not possible / filament not making it into hot end to do this.
You can see little bit of filament sticking out in photo, but with pliers this just tears.
Should I try heating up the whole hot end tube with a soldering iron to see if I can liquify the clog out?
Any other ideas? I can't find many good resources about what to do in this situation online.
Also, obviously needs to get cleaned up a bit, but does picture of my hot end tip look pretty ok? Do I need to bite bullet and get a new hot end? If so, are Amazon off brand replacements ok, or do I need to wait for one to get shipped from prusa?
Thank you
Out of the wider backend side.
Heat the nozzle end, it will create essentially a bubble at the side and start pushing everything out the other end (some will come out the nozzle, but since it is such a narrow opening it is easier for the filament to flow backwards), as soon as you see it start to come out the back end stop applying heat and gently pull on the part the gets pushed out.
If you go too quickly and separate the solid bit from the molten bit, quickly push it back in and try again. If you can't get the two pieces to connect, apply a little more heat and keep trying.
