just switched to a roll of SUNLU PLA in my ender 3 v2 neo. I had some adhesion issues that were fixed by leveling the bed, somehow the whole left edge dropped down.

anyways, I printed a bed leveling calibration thing and this happened, one single corner started curling up/unsticking. you can see it happened on several passes, but can someone tell me how it only happened at this one corner? the whole rest of the shape is uniform.
