Amastone, started from a stone background, but my cnc they built for stone, wood and brass. I have found them very helpful. Ias fas as I can tell most of it is down to spindle spec! They made mine in a special size as I only had a narrow place to put it and in Stainless Steel.

I would be interested to see where you end up with what you are doing both machine and software wise...
