Auto level issue after firmware upgrade

[tplindley 0]

I just updated the firmware in my U3 to current stable. Since then, the auto level feature is not working. I go through the process of manually leveling the bed then try the auto level feature and it doesn't get the nozzles close to the build plate. Then responds with the "out of reasonable" error message. How do I get auto level to work again? Thanks.

Hi,

the first thing I could imagine is an incorrect distance between the top of the base plate and the bottom of the heater plate, which should be approximately 14 mm for the auto leveling to work properly.

There exists a distance tool for easy adjustment:

Which error-number is the "out of reasonable" attached? Perhaps there is a helpful description and solution on the UM homepage, like for example this:

Does your capacitive sensor work properly (can be checked in the diagnostics menue since last firmware)?
