Height Map scaling

[too]

Hello people,

normally on a FFF machine, a 0.25mm difference on the build plate is definitely noticeable, so it makes for a good minimum and maximum of the scale in the heightmap window.

However, I am using the duet to control very very large machines that will map out areas with significantly more differences in height.
When I am trying to look at the heightmap, it is very much distorted:

The attached picture is a heightmap of a small area, 3m x 4m. Once there are more points and the area increases, the entire thing gets even crazier.

What I am suggesting is a configurable scale for the heightmap, changeable somewhere in the settings
