Lots of good info for starting a business. But for me CNC is just a hobby. I realized that I could use one in the shop. With zero CNC experience I ordered an entry level 6040 from Ebay. It took 2 months to get it hooked up and cutting 3D relief items. Now I'm making all kinds of 3d reliefs. First pieces were pine. The type of wood makes a big difference in the quality. So now only cherry or walnut.
