Stringing/Oozing Ugly
I used to get nice clean prints with this model, but recently I am seeing artifacts that align with the stringing/oozing talked about in the Simplify3d Print Quality Guide.
They recommend increasing the retraction distance (although Prusa's guide says anything more than 2mm is a waste). I've also increased the retraction speed AND lowered the extruder temperature.
All these changes have had no real effect - I continue to get this stringy/ugly look.
Any ideas? I also have 2 Prusa MK3s and I get the same results on both using 2 different brand filaments.

1st thing to try is another filament. If you didn't get stringing originally and do now, humidity impacting the filament is a distinct possibility. Dry your current filament, or try a fresh spool that has been stored properly.
RE: Stringing/Oozing Ugly
Using a different brand filament (PLA+ from eSun) works much better. Not perfect but acceptable.
I've tried different PLA filaments and they both ended up stringy.
So, PLA+ works, but PLA does not. I'd love to tweak settings to get the PLA to work.
RE: Stringing/Oozing Ugly
IF that same PLA worked better before, tweaking settings will only do so much. Consider drying the filament out.
To reduce stringing, try disabling Printer Settings->Extruder 1->Retraction->Lift Z (set to 0). That may improve stringing, but you may get stop surface scarring as a result. I am getting good results with theses settings:
Again though, if you're trying to compensate for deteriorating filament with hardware settings, you're only going to get so far.
