Use Heightmap checkbox disabled, why?

[Jodank]

Ok, I was trying the Heightmap option in this version of Candle, whenever I finish the measuring of the pcb everything is fine, but the checkbox "Use Heightmap" is non-stop gray. Why?

Will this function automatically correct the Z depth when I try to mill my pcb after I measured the surface deviation or I have to do some other thinks too?

What I doing wrong? Thanks.

You need to load G-code before you can use it. The checkbox still remained disabled for me, but I could run the hightmap function by pressing the 'Create' button.
