Continued issues with printing
Greetings.
I am having an issue where I start printing and at some point in time that is always random, the Nextruder starts clicking like filament is stuck. I have watched it, and it looks like the filament is not extruding any filament from the nozzle. I pause the print and open the nextruder door to see the filament is snapped. So, I cleaned out the broken bits and powder, blew it out really good, pulled out the nozzle and get the stuck filament out of there and tried again for the same result.
Additional information -
- I run dry filament in a dedicated dryer, it is PLA+ from Sunlu and the same has happened when I switched to eSun and Inline (Microcenter).
- I resliced the model incase anything in there was corrupted, although I thought that was unlikely, with no change.
- This started happening only a few weeks into using this semi assembled machine and the first 2 weeks it printed flawlessly.
- I am not a newb - I have 3 Mk3S+ and have been printing for 3 years.
Has anyone else had this issue and been able to figure out what the heck is going on? Very frustrating for a machine of this cost and quality.
Are you sure the filament is dry and has always been dry?
If PLA is left wet for long enough (weeks) it can micro-crack and become very brittle. Later drying doesn't cure it.
It can also happen with UV light exposure but you'd usually notice surface deterioration on the spool.
Cheerio,
RE: Continued issues with printing
I can take the piece and fold it back onto itself and at the bend it doesn't crack. This toll was in a dryer before and during the print, which is my typical practice.
So, yes. I am sure.
side note- I am looking more at the nozzle now. It is acting like there is a piece of ptfe stuck in it.
