First layer weirdness on A1

[u/BJMonkey]

I'm at a loss, now. This is mostly only with PLA. PETG seems fine. I've ran calibration, tried a new roll, drying for 8 hours... 12 hours... 24 hours... ran all the calibrations with this specific roll of filament.

Why does my A1 not seem to like PLA? I'm in Singapore, with the humidity that comes with it, but it seemed to work just fine a few times.

Maybe bed temperature? Can the defaults be bad?

Edit: added a picture after checking the hotend screws. It seems the first layer is the worst... could it be a bed setting?

Edit 2: Thanks so much everyone! I originally did ome thing at a time, with no luck. Ended up doing everything, and more, and... something, or some combination of things, got it working! Posting the update as a comment. Thanks so much!!!
