Hello Dan. Im doing this a bit backwards. Im getting the software to master before I buy the CNC machine. Ive done down the route of Vectric Vcarve Pro. I did try Carvo co but it seemed a bit fiddly compared with Vcarve Pro. Vectric do a higher version called Aspire but to be honest, you would need to be making very high end stuff to warrant the price of that software. You can download a test version of Vcarve pro to have a play on. Let me know if you need any help with it as I'm getting quite good on it now.
