I really don’t know whats happening. Especially with the Over and Underextruding… Heck the Bottom Left pic shows both happening basically right next to eachother… whats going on?
(The Printed Model in the pic is just the Entire First layer and buildplate printed in. Letting it Run a Third time now to see if the Patterns stay the same)
That is a bed leveling issue. It’s too far away where there are gaps and too close where there is rippling. Run a bed leveling procedure and if the model allows for manual leveling you should go through that and then do another mesh leveling.
Also clean your build plate with soap and water and avoid touching it with bare hands.
