Help with major clog in bb 0.4mm nozzle


Recommended Posts

Posted · Help with major clog in bb 0.4mm nozzle

Hello all,


My new BB printcore became clogged after only a few uses, and nothing I've done so far is able to fix it (multiple hot/cold pulls, trying to force extrusion).  It's gotten so bad that even trying to heat the core and extrude by pushing filament doesn't cause any extrusion.  

What should I do?  Should I try to remove the nozzle head and clean from there?  I'm very disappointed right now, as nothing like this has happened before.
