Hi there, after I adjust z offset as (-3.35mm) my BL touch moves to 13.35mm as displayed on the LCD to start probing for home, after probing is finished it stops at 13.35mm and then it changes to 10mm even though the probe stops moving at this point. It results in my prints being 3.35mm above the build plate. The z-offset still displays as -3.35mm. I have attached a video of the issues. 

Thanks

You have to adjust the z offset based on Z=0. when you "Auto home" the Z position may not 0. Please check "Move" after you auto home, you have to make sure Z=0 before adjust the z offset.

Hi, the z offset is calculated based on z=0, but when I auto-home, it just overrides the z offset.

I am also confused. Seems something wrong with the firmware instructions.
