Optimising quality of prints
New Ender 3 v2 owner here and been having fun with my first few prints (benchy, xyz cubes, octopus etc and a few home made designs as well )
Now that I am getting the hang of it and the initial excitement at the first prints is worn off I am looking at the quality and starting to nit pick.
I have gone back to basics and the 20x20 5 square test layer - https://teachingtechyt.github.io/calibration.html#firstlayer
what I get is a pretty good layer I think and I believe the bed is level and at the right height but I get these artefacts on the surface that I can't seem to eradicate. The Squares are in the same position as the print out. What is weird is that each square has a slightly different area of "imperfection". Am I just hoping for too much from this printer with PLA or is there something obvious to the seasoned 3D printers that can be done to tidy this up?
Thanks in advance
