So, I’ve had my mini for a little over a year now, and it has been a constant source of joy in our household. A couple weeks ago, though, the nozzle clogged up in the middle of a print, and I am out of ideas on how to fix it.
I read the official page about unclogging hot ends, but it seems to assume that I can get filament down into the melted part and use that to pull some out. So far, I haven’t been able to. It broke off flush with the top when the nozzle clogged and while I’ve been able to get some of the filament out between tweezers and a drill, I can’t get the filament down low enough to where it would merge with what’s melted.
I tried melting the filament on the side of the hot end and sticking it down the hole, hoping it would grab onto something – no dice. It gets stuck, but not well enough to pull anything up.
I tried sticking a safety pin up the nozzle, both hot and cold. It can’t get very far, and doesn’t seem to let anything through.
I’d cheerfully clean out the nozzle with a screwdriver or something if I could get it off, but the instructions for getting it off and back on are a little intimidating, and I’m sure it’s even worse if the thing is full of hot plastic.
I thought – well – I’ll just replace the whole tool head. Those instructions don’t look too bad . . . and it turns out the store’s out of the one I would need!
I’m not sure how it got stuck. I’ve only ever used filament from the Lulzbot store with this – occasionally HIPS, occasionally PLA. I had just finished a print with some blue PLA and switched over to the red HIPS. It got about an hour into the print before clogging up. For a while, I could get to extrude the tiniest little pig tails by pushing really, really hard on the top. Now I can’t get it to do even that anymore.
Does anyone have any last ditch methods for unclogging a nozzle? I really miss my printer.
