@beadster same thing happening to me .
I've tried with different nozzle in position 1 and 2 .
Changed the capacitive board and glass bed .
plugged and unplugged the front fan without any change to the Leveling sensor test and value , they are around 1 and 2 .
I've manually leveled the build plate , reset to factory and no change at all.
So to make it run , i've disabled the adaptive leveling ... by connecting in SSH ... ( not recommended )
I'm waiting on a solution to make this works ... pretty frustrating to see this 9K$ printer not being able to have an adaptive leveling working when my Elegoo Neptune 4 with klipper is able to make a bed mesh and everything for 300$
