I just got finished fixing some weird oozing problems. All the settings I tweaked, the best I could get still had stringing and blobbing at the end of every layer.

Turned out my hotend had fragments of bowden tube clogging it. I don’t know how, but assume I had the heat cranked too high at some point. There’s no real cleaning that out, and I ended up replacing the entire hotend.

I also had a clog or damage or something causing heavy resistance in the pull-tube going from my spool to the extruder. Replaced that too and everything is printing beautifully again.
