Ich brauche Hilfe für 3.1 400.
Mich irritiert auch „unterschiedlich fest“. Ein Video würde sehr helfen! Rein ins Blaue geraten: recherchiere mal den englischen Begriff „binding“ in Kombination mit CoreXY

Wobbly/uneven walls
I get similar artifacts printing PETG and not cooling properly (e.g. keeping my enclosure closed during a long print)

Smudgy/ripply top layers & solid infill
Okay - finally some new insights:
I am now at a stage where i can rule out two major culprits of my prior prints:
1) warping
2) thermal x-gantry issues
Both got better with a heatsoaking script. I did heatsoaking before, but i guess my manual approach was not good enough.
Additionally i calibrated first layer squish, which has major effects on top surfaces.

Over and underextruded solid top layer
For the wavy patterns on the bottom right: I have similar ripples on a testprint of mine i can prove to result from warping. -> what @TheTik said...
Try the following: Put your print on a planar surface. Apply a little bit of pressure with your hand from top and at the same time try to slip a sheet of paper between the surface and the bottom layer. On my testprint the paper slips under the print where the ripples are on the top layer.

Smudgy/ripply top layers & solid infill
Not really:
I followed https://ellis3dp.com/Print-Tuning-Guide/articles/first_layer_squish.html and realized that the first layer squish has quite an impact to top surface layer quality, even if the top layer is in a higher layer with sparse infill below, which allows the filament to relax. I also learned that the stock print bed is quite tolerant to first layer squish.
In the pictures i posted i printed with 3 top layers. The finishing, smudgy layer is printing significantly slower. The layer before has a lot smoother surface than the final layer, which could be a sign that i don‘t fight with thermal x-gantry issues, but i can‘t prove it yet.
I also need a more structured approach to this issue - there are yet too many variables. I implemented a heat soak script (did it manually before) and (can someone confirm this could be an issue?) do my tests with a stable room temperature.
Btw.: happy new year and trouble free 3d printing 😉

First layer problem
In your printer.cfg is a macro section which should look like this:
[gcode_macro _START_PRINT_BED_MESH]
gcode:
BED_MESH_PROFILE LOAD=ratos
Also make sure that the mesh you'd like to use on the "heightmap" tab is named "ratos"134 replies

Check in your printer.cfg that the correct bed mesh is loaded.

Using Raspberry Pi GPIO header pins from RatOS/Klipper
Here is my solution for future reference:
It seems that RatOS is preconfigured to use the Raspberry Pi as secondary MCU, but does not import the necessary configuration. The good news: everything is already there!
Just include the config file:
[include config/boards/rpi/config.cfg]
From now on you can refer to your Raspberry Pi as secondary mcu with the name "rpi". Feel free to have a look at config/boards/rpi/config.cfg for further reference.

Using Raspberry Pi GPIO header pins from RatOS/Klipper
Yeah! Right! Thank you so much for your help!
After a few github searches: It seems that RatOS (https://github.com/Rat-OS/RatOS-configuration/tree/v2.1.x) does not import the Raspberry Pi config file by default (never?). Is this correct? I'm sure there are reasons for that, but maybe this is something to add to the default config file (commented maybe), or even make this a question in the dialog when configuring the initial installation.

Ok - seems that i solved it, but there are still questions.
I added the mcu (again?), which made it work:
