I’m having a lot of trouble getting prints to finish, so any clues, suggestions or encouragement will be greatly appreciated.
The filament (PLA, 180 deg, 50 deg) is now stuck in the extruder (.35). On this day the first print stopped extruding after about 10 mins. So I stopped the print, pulled out the filament (with difficulty), cleaned the knurled gear and pushed in a fresh filament end. I was able to manually extrude so I started the print again. This time it ran for about 5 mins then stopped extruding. I tried to pull out the filament but it is stuck. I heated it to 210 and tried to pull it out with pliers (even leveraging it against the frame) but it is stuck. The only plan I have now is to remove the extruder and then try to remove the nozzle and soak it all in acetone. Has anyone else had this problem or have other suggestions?
Sometimes the printer stops extruding because the filament spool gets stuck. I the have to try and unroll enough to get started again and then every 15 mins have to manually unroll until it’s done. This is very annoying for a long print. I don’t have this problem with ABS, only PLA. Is there something I can do to prevent the reel from getting stuck?
If a print happens to finish (rare), the last layer is very rough. I think I saw a suggestion on how to help this but can’t find it now. Any suggestions?
