Help with major clog in bb 0.4mm nozzle

[Tiger91 1]

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.

 

Thanks

Have you used cleaning filament sticks, or if you have it transparent PC?

That works best.
