Is there any reason that the tinyg auto level feature should not work on

Is there any reason that the tinyg auto level feature should not work on larger material such as aluminum sheet for milling operation rather than PCB milling?
We are using mm and not inches since I understand inches are not currently supported?

Auto-level should work like a charm on that. The most amazing use case I’ve seen is somebody wanting to mill a rock and they laid aluminum foil on it to probe it and it worked great.
