It will do exactly what your looking for (compensate for differences in Z height). I know this doesn't help with Mach3 but development of Mach3 ended years ago.Thanks, when do you expect this to be available?
The MapSurface wizard is pretty slick. You can set the min and max positions to map in X and Y, set the resolution of the units and mapping grid, select the one of 4 possible probes you want to use, etc. You should also be able to lay a map on top of another map. In other words you could do a coarse mape of a big table (say 5' X 10') at something reasonable like a 6 inch grid. Then when you want to do a highly accurate area (say 3" X 3" for a PCB) you could map just that area at some insane resolution grid (like every .010 inch) and enable that map to route your PCB. Here are some screenies of what it looks like.
Since the map points are dependent on knowing where the X, Y and Z are you get a warning it any enabled axis hasn't been homed (referenced). You can ignore it (but i wouldn't) or leave, reference the machine then run it.
