Thnx, I forgot all about that override-file.
I'm still confused sometimes with Duet, comming from RAMPS / Marlin.
Can the override-file be considered the same thing as EEPROM was in my Arduino?
Where can I find general info about the file structure and what they all mean?

Hi all,

after using the DUETwifi with great pleasure for a few months I updated my Delta printhead and effector. The whole setup is about 12 mm shorter now resulting in more print height. Problem is that now the auto bed leveling wordt reach the FSR system anymore.
I"ve increased the M665 hxxx setting to 12 mm extra but somehow this seems to be ignored. The head stops higher than usual, then decends and reports that the z-limit is not triggered.
WHY?

all help welcome, thanks in advance.
