3D g-code file help

I’m ready to grow into the next level of cnc carving and need someone with experience in carving 3 dimensional signage. I basically have a ZBrush sculpted logo file exported to .STL and need to properly turn that into g-code and import the final file into v-carve.
I’ve used this workflow using 3D printers very successfully but am new to doing it in cnc. I’ll be using a Shopbot initially since my x-carve is not running at the moment.

Anyone with this type of workflow experience willing to help advise me would be greatly appreciated.
