I have another one if neccessary, but I think the screw shafts on it are clogged with plastic, so it might take some work as well.
If you can connect it back and heat it up to regular printing temperatures, you should be able to do a so-called “cold pull” that should fix it.
I tried this, but the filament doesn’t seem to fuse or connect very much; I also tried with this thing
and I also didn’t seem to be able to push it into the hotend through the extruder.
Thanks, I’ll try this.
My old i3 clone came with a 1mm steel rod I use in these situations. Leave the extruder on your printer, cut the filament off, heat up the extruder to a normal printing temp, and push the gunk through the nozzle. If you have a cold side clog you’re probably going to have to add heat from something like a heat gun.
@Interstellar_1 Bambu has documented a procedure that works flawlessly when I’ve used it. Don’t know if it can apply to your hotend or not. Look for “hot hex wrench unclogging method” on this page. https://wiki.bambulab.com/en/x1/troubleshooting/nozzle-clog
Thanks, after inspecting the clog this seems like the ideal thing to try. I also think I might know how this happened now too, the filament dryer might have heated the room to a temperature where heat creep was easier.
Blowtorch, just be careful of the wires and try to get the thermistor and heater out first.
I’ve used the torch and cold pull methods successfully, but have had great luck with a cheap set of acupuncture needles from Amazon. I would pre-heat on the printer and just poke the needle in there a bit and feed filament through.
put them on a sheet of aluminum foil and put them on a cookie tray in your oven. set the oven to 450 degrees and bake it for a half hour plus. everything should melt out of it. you could even suspend it with a rolled up piece of foil under it. depending on the wires your thermistor may suffer but the heating element should be fine. tho, your thermistor probably will be okay too as it looks like it has silicone covering the wire.
This sounds potentially dangerous
I don’t know. I’ve use this method several times and I’ve never had a problem. I probably should have specified that I’m in the states so 450° f versus 200 or 210° c that your printer runs at isn’t a huge difference. Sure. You run the risk of some fumes, but your printer is already belting the plastic. In that temperature. You need to go a lot hotter than 400° in order to set it on fire. It’s a lot safer than using a blowtorch
Ok that makes more sense. Sometimes I forget that Fahrenheit exists lol
