Hi all! I’ve been scratching my head for a while now trying to get this figured out. I’ve got Klipper installed on my Elegoo Neptune 3 Pro, and I’ve never had perfect bed meshes. The back left is still too close, the back right is still too far.
The images show the difference between the corners (My Z-Offset was too close on this run so it’s squishing too much all over, but the difference is still visible).
I recently installed kyleisah’s Adaptive Meshing & Purging in hopes of this being a better solution, and I’ve put my tension up to 0.5, but have gotten marginal improvements. I’ve also attached my printer.cfg. The Bed Mesh values at the bottom can be ignored, since the adaptive meshing gets a new mesh every print.

Range is 0.7. Not great but not as horrible as it looks in the display.
I’m not familiar with the Neptune and how, if at all, you adjust the bed screws but getting that range nearish to your layer size should do wonders.
I know this is a couple days old, but I have a heavily modified Neptune 3 (non pro) and it needed the bed springs that replaced the plastic spacers. It was very uneven within a month or two of owning it and was constantly shifting.
Bought a pack of springs for maybe 10 bucks on Amazon and, while not as permanent as solid metal spacers and maybe loctite, it lasts much longer than the plastic spacers between needing a relevel, and being able to fine tune it with a screwdriver is a must.
