@fcwilt Hello two speeds are where in firmware please?
From the docs:
From RRF 3.3 you can provide two F parameters instead of one, where the second is lower than the first, for example F1000:500. When doing a plain G30 command, an additional probe will be done using the first speed to establish the approximate bed position, before one or more additional probes are done using the second speed. The first speed will not be used when probing at a defined point or when mesh bed probing.

Could you elaborate a bit on that?

@phaedrux Any simple gcode for leveling? I edit G28 gcode too.
Do you mean to level the bed, or to create the mesh for the surface?
Maybe this helps to explain

@fcwilt G32 works fine, but G29 has problem, so mesh.g

That looks pretty good. Are you still getting the error about the offset?
Have you done a test print with it active to see if it's working as expected? -
@phaedrux Looks good, but what about the four points in corners? I started printing yesterday and first layer looks good. Object was in the center of bed and has diameter 150 mm.

A 5 by 5 mesh grid can give a false impression of the bed surface.
I use a 20 by 20 mesh grid.
Perhaps create a new height map using more points.

Thanks guys, I fix it.
