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)
Has it always done this or is this a new issue? I agree with what someone else said, I think this is likely a bed leveling issue. The P1S uses pressure sensing using it’s nozzle for bed leveling. If the screws holding the hotend in place aren’t tight enough, it might be giving you poor readouts. This could happen after a nozzle swap if you’ve done one before. Same if the print head itself has a lot of play in it for some reason, it would throw off the results.
