Major issues with klipper and bed levelling (feddit.dk)

I recently made the switch from the marlin-based stock firmware on my anycubic kobra 2, to klipper. I didn't have issues with bed levelling or first layer on the stock firmware, but I'm having significant issues running klipper. The bed is uneven, the probed mesh shows a deviation of 0.197mm, it was the same when running stock FW+octoprint.

But it seemed to be correcting just fine for this on the stock FW. I got a consistent decent first layer across the entire bed.

With klipper, it's absolutely impossible to get it to correct for this unevenness. Half the bed will get perfect first layer, but then the second half is either way too squished or hardly connecting to the bed. And it's causing further issues as it's also hitting the print when moving, despite having Z-hop of 0.3mm for travel moves.

What the hell is going on? How do I fix this?

I'll try to check mine when I'm back home later. I just use the default profile since I don't ever adjust anything with the bed unless it's out of spec. Even printing at slightly different temps doesn't seem to affect anything as far as bed leveling is concerned.

Yeah I'm not seeing any significant deviations in the mesh based on temps either.
