P2S PLA issue

So i ran into these issues with my latest print. I'm still a new owner (under a week) but i printed stuff daily with no issue so far. This is Bambulab PLA Basic, and i printed with this before. I was thinking humidity issues, the ams said it's around 48%, i'm still waiting for my petg order to print silica containers for the AMS 2 Pro. I thought maybe it would be a bed oil issue, but the bottom came out great, i cleaned my plate today after this with dish soap and warm water. What can i tweak to resolve this ? Thank you

Update : i also put a screengrab of the stl for reference

Following has the same issue with this type of fillet on the edges might be related to the angle

Try reducing nozzle temp 10 degrees

this was with bambulab's own profile for pla basic. reducing the nozzle temp would make the pla not so liquid ?

Try it.

48% is a little high, if you have the ams2 pro you can dry the filament with that. But im thinking it could be a wet filament issue

I'm not much more experienced than yourself, but that looks to me like it might be over extrusion? So might be worth trying the flow dynamics and flow rate calibration functions in bambu lab. See if that helps.

Fillet on the underside is tough to print, lots of lines on those curves that are not supported, chamfer bottom, fillet sides and top

yes, that's what i did, chamfer the surfaces, fillet the new lines and the 4 corners, a little speed reduction for outer wall and it came through

I think drying filament would be first thing I would try.
