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)
Left field suggestion, also: Make sure there isn’t anything trapped under your build plate. If you have any shreds of filament or flakes of old supports or whatever between the steel plate and its magnetic base, the surface won’t be flat to a degree that the auto leveling probably won’t be able to deal with it and you’ll get all kinds of crazy unpredictable results.
I did this on my Qidi once. I’m glad I noticed before going crazy with troubleshooting. I had black filament scraps on the black magnetic base, which were practically invisible and I only found them by feel.
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.
Looks like leveling issue indeed. In some places nozzle scrapes the filament from the bed being too close and piles it up and in others the distance is too high so it doesn’t expand enough on surface when leaving nozzle to connect with adjecent already printed lines.
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.
Need more information to properly diagnose. Is this a new issue? Are you using auto build leveling for every print? Have you tried cleaning everything and rerunning the system calibration? A lot of different things can cause similar issues and it’s hard to diagnose from images alone.
Check your extruder tensioner and calibrate bed level?
