In my first picture is my current print where I'm having these weird waves going. Everything should be calibrated fine, as my print is largely sticking to my bed, but I don't understand why I get these waves. In my second and third picture is top layers from a previous print that I decided was good enough to start trying to finish despite the fact that it seems my printer can't do top layers very well. Most likely fixable post-process but I don't feel like I should have to be doing that as much as I am. What setting should I change to make my prints first and last layers more stable?
