G31 Z height and babystepping

[pipersw]

Hi,
I have in G31 a Z height about 1.74mm, and during the first layer le nozzle hit the bed.
I have to set babystepping to -0.5mm in order to have a good nozzle height.
So, in G31, I have to add or substrate the babystepping value ?

I think substrate, because the Z height have to be higher, so 1.74mm + 0.5mm = 2.24mm.

I am right ?

Increasing the G31 Z parameter (or making it less negative, if it is negative) will move the nozzle closer to the bed.
