My mini was printing awesome for 6 months and then it started pooling filament globs around the nozzle. It appears to be leaking filament from between the nozzle base and the metal cube part it is (screwed?) into.

How do I fix?  
Heat up and separate? Let cool and chip away at hardened filament?

Thanks for ideas!

I would follow the directions in this post…

Remove the nozzle, clean thoroughly, and replace while heated as mentioned. That should seal it up and prevent further issues.
