Re: Which CNC for cutting?
They make a knife holder( spring loaded) for holding the vinyl blades that can be used on a CNC router. I think they are about $250 USD, dead simple to figure out and use. I made one for my CNC plasma cutter a long time ago and it worked beautifully. Your Z motor on a CNC router does the up and down movements for you, the one you have pictured looks expensive but maybe you don't mind. I think if you had a CNC router the knife setup would work, it does for vinyl anyway. Sandblasting media vinyl is what you need to ask about cutting.
