[SOLVED] Extruder clicking (lemmy.world)

Is there any reason that little silver part of the extruder wouldn’t move and start clicking while printing when printing at 205 in PLA. It seems to turn just fine without any filament in there otherwise.

I cleaned out a nozzle clog, but is it possible there’s junk in the hot end stuck?

Resolution: Thanks for your help everyone! It ended up being a nozzle clog that I didn’t get all the way out. I ended up heating the printer up and doing the cool down trick. That seemed to work as a last ditch effort before buying a new nozzle.

It looks like I can’t extrude in the air either. Maybe I didn’t get all the gunk out of the nozzle the first time I’m just clueless on how to. I tried soaking it and acetone and digging stuff out and that didn’t seem to do it and the only pen I have doesn’t go through the hole in the nozzle. It’s too thick. It’s sitting at about 240 right now so I’m hoping That it just melts I guess.

At this point, I’m wondering if it’s not just worth buying a new nozzle and calling it a day

Heat the nozzle up to like 215C and then shut it off. Wait for the nozzle temp to reach 90C and then yank the filament back out. If you do it correctly, the very tip of the filament you yanked out should be a fine cone shaped point. This is referred to as a cold pull.

It is not really worth it trying to clean a clogged nozzle. Just toss it and replace it.
