    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
