Factory Assembled Core One+ Nozzle clog?
Hello all. I am looking for some answers before I go crazy trouble shooting. I just received my Core one plus the other day and have successfully done a few prints. At the same time, some have not been successful. My prints fail sometimes 50-90% complete when the printer stops extruding and just clicks. If I wait about 10-15 minutes, I can go to the menu and purge material from the extruder no problem. The temps never fluctuate to where I can see there's a heat problem. Attached are some pictures of the completed and not completed projects. Also the filament is prusament pla. Just trying to get options before contacting support or continued r&d. Any help is always greatly appreciated.
RE:
You most likely have a nozzle clog. PLA can do this on a Core One due to heat creep. Try to do a cold pull (there is a wizard for this on the UI screen) to unclog it. If you are using the high flow (CHT) nozzle, these can be difficult to unclog. Once it's unclogged, try printing with the door open. Also, I would pick up a second nozzle. I would recommend a non highflow Obxidian or Diamondback. Yes the Diamondback will be stupid expensive but you'll never need another one.

I did a cold pull and loaded the Prusa Galaxy black. I also cracked the door as you suggested. So far 2 prints and no hiccups. I actually did buy the obsidian .04 and a diamond .06 nozzle from Prusa as eventually I’m planning on printing some carbon and what not. I will replace the nozzle here shortly I just wanted to get a hang of everything first. Thank you very much for your reply sir!

Cool (pun intended). The issue with PLA inside a chamber is toward an end of a long print some brands can soften beyond the heat break. Then the Nextruder gear flattens it into an oval shape and then it no longer can fit in the nozzle causing a partial clog until pressure builds up and forces it through. It's for this and other reasons why I don't bother with PLA anymore.
