Can someone help me troubleshoot? Seems like it's sticking to the bed, but not well, as lines are somewhat wavy or lifting. Is it related to adhesion? Or maybe I need to clean my extruder?

I think I'm levelling the bed too close to the extruder. Maybe it's rubbing or the heat from the extruding is warping it.

    $\begingroup$ Your nozzle is probably too close to the bed, use a thicker piece of paper. Please look at this answer, it describes what to do against the waves in the first layer. $\endgroup$
