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?

The audio might be a clue for you to help me troubleshoot

    Umm, disclaimer, no experience with 3D printing, but…

    Could humidity or dust on the print bed perhaps be an issue?

      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.
