I left a print going last night, but in the morning I found that only half of it was printed, no rats nest of filament anywhere around it. what I think happened was the extruder was no longer able to pull on the filament spool (which is on a crappy external holder) that apparently fell apart mid print. But now it won’t extrude filament; I tried a test print and the lines of plastic are much thinner and sometimes even don’t come out. I worry that during the rest of the print last night the little feeder wheel inside the extruder ground down on the stubborn filament. I unloaded and reloaded the filament and I keep getting these clicking noises when I’m feeding the filament down. It’s a flashforge dreamer.
does anyone else have some insights into this problem? where can i find parts to replace the feeder wheel or anything else that might be broken?

Sounds like it might be as simple as a clogged nozzle. Have you changed it before?

yea, ive replaced the nozzle before. ive already taken it apart, and i think its the nozzle too. ill replace the nozzle and see if that fixes it.
