<p>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? </p>

Your nozzle is probably too close to the bed, use a thicker piece of paper. Please look at [this answer](/a/7232/), it describes what to do against the waves in the first layer.

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.
