3 axis or 5 axis??

That is great news, thanks. My sense is 3 axis would be fine.
A laser would be helpful in that it (just thinking outloud) may be more precise. For example, say you have a piece of aluminum and it has a pit here and there. The pit may .2mm in diameter and .5mm deep. The sanding head will need to sand either all of the material away to remove the pit or create a blend to a non-pitted surrounding surface.
