What kind of machine will do stainless steel or brass engraving

[Tenson]

Thank you Jonathan for your advice.

I've been looking at some options and ran across Redsail,Cutting Plotter,Vinyl plotter,Vinyl cutter . I will contact them directly to see if theirs can do the job. Its a bit more money, but it also seems to be a good price for a much larger machine... Perhaps they well run a test.

That looks crazy good for the money! Profile rails on all axis, steel construction (though can't see geometry under the covers of the gantry), flood coolant ability. Very nice indeed. Though I just noticed, only one bearing block per rail on the Z axis... possibly on all axis!
