I would like to get a CNC router, and I see that there are many options on the market. I have zero experience with CNC, but I am able to use tools, computers, design software, and hopefully anything else that needs to be done to be successful using one of these machines. I have been looking at the C-Beam, the OX, and also complete kits like the Shapeoko 3. Are there a lot of differences between these machines? Any insight is greatly appreciated.
