I've printed hundreds of prints over a few years. Now I haven't printed in a few weeks but this is the first time I've had a problem like this. This is supposed to be flat. What's happening?

It's warming up here and humidity is rising. But it's never been a problem before and as I understand humidity is more of a PETG thing, this is just PLA

While PETG certainly has a lot more moisture problems than PLA, PLA can still give you a lot of grief if it isn't dry enough. Stringing, oozing, uneven extrusion, and many other weird problems. I would definitely try to dry the filament...

But this could also look a bit like over/under-extrusion... Have you tried calibrating your e-steps?

@akilou @over_clox Nono, PLA is also sensitive to humidity. I have seen similar things with filament that I know is dry, so I think it must be something else, and I'm curious what it is.
Overextruding? Have you changed the filament? Sometimes they flow a bit differently.
