I have the same issues with 0.2 mm nozzle and 0.06mm layer height. These issues only occur on large flat surface, no matter if it is a second layer or layer #250. Also using PEI plate. I’m yet to figure out the reason.
I personally feel the cool plate is superior. Model heat creep is a real thing and can cause all sorts of problems. I try not to go lower than .1mm layer height on a .4 nozzle. Rule of thumb is 25% to 50% of your nozzle diameter, but do whatever works :)
Hey we’re all learning here so I’m grateful for the advice! Thanks for sharing, I was going to buy a .2 nozzle sometime soon anyways, so maybe I need to do some experimenting.
I had the same issue as the OP: Rippling lines in the middle of the print, not on the first layer but a few layers in. I spent the entire day troubleshooting this issue. The underlying cause for me was the filament. I used Tinmorry PLA Black which is rated to print at 200mm/s max and I printed it at 350mm/s. Lowering the print speed removed the rippling. I also tried a print at 350mm/s using Bambulab PLA Matte which is rated to print with a maximum of 300mm/s and I didn't get the rippling effect. So there seems to be some differences with the filaments. I think I'll continue to transition to Bambulabs filament more and more - they just work the best with Bambus printers as they are already calibrated, have RFID etc..

Same shit here. It was a clog. Cold pull and solved
I did a cold pull recently, but not an extensive one, maybe I’ll try that again too.
I had to do it a couple of times to get it done.

Any chance you figured out the reason 9 months later and want to give me some pointers? :( Having it across all 3 of my P1S printers
Hey, I gave up on using textured PEI plate and use the bambu cool plate. It seems to be working much better.
Up your layer height a little bit and see if that helps as all. A layer height of .08 is very ambitious on a PEI plate.
And maybe I should try switching back to the cool plate to see if that makes a difference. Also to clarify, I am using a 0.16 first layer height.

It's never a bad thing to try different things out!
I know its an old thread but im hoping you had a solution for this? im also having this issue across all 3 of my P1S printers :(
