always starts lifting z+ 38mm

[tecdroid]

hi,
I just downloaded autoleveller and tried it but it always starts lifting my z axis 38mm. dunno why.
The point is, i got only about 30mm left (wooden scrap plate plus pcb, etc.)
where can i change this?
i use the free version.

I think the setting you want to change is the "Probe Safe Height" on the Mesh tab.
