@M0YNG @3dprinting You really need to get a clean print where it's not failing to adhere and getting dragged all over the place in order to be able to read it.
Corners are also a dubious way to tune PA because it's only one of a large number of factors that can affect how they bulge or round, but if you get this to print ok you should at least be able to choose the one that looks the most consistent and have better results than fully untuned.
