If your building your own CNC mill or upgrading one you have you'll have to deal with some sort of CNC controller. This instructable is on the CNC controller I ordered and the case I needed for it. I designed this case and laser cut it ( I made it at TechShop - Check them out at http://www.techshop.ws
) you could also CNC mill it (of course). I'll take you through this step by step with links for box files, box creation website and photos.
