Corner dip. Bed level with PAM. Uneven first layer. i.e. perfect layer one side, opposite too close

I have a problem that when laying the first layer, it does not seem like PAM does anything or not enough to make the layer perfect.. Do anyone know what is wrong here? And how it can be fixed?

Same problem here on my 400. Weird ripples on only part of the print.

I can post some later tonight. I was getting the same effect on my troodon 2.0 as well which is very odd. The only thing similar about the two is they both run klipper and I updated klipper for both at the same time before these layer tests. Hmmmm I did try a drier filament on the troodon and that seemed to print just fine though it was not a layer test.

The archim pattern for some reason didn't have the problem or maybe it was on a different part of the bed.

Walls seems to be fine, it's just monotonic infill maybe?

Have you done a beacon_mesh_calibration ?

Adaptive beacon mesh is now automatic at every print and has been for awhile Despite this weird first layer business I did manage to pull off a 12 hr print with a large first layer. The Pic is of that print. The filament was pretty wet though so for me that might have been a factor A clean z offset calibration with the nozzle wiped clean with a wire brush did the trick it seems.
