All future Upgrades/AddOns will be backwards compatible. The initial backers are how we got where we are today, and we want to insure they are always shown the appreciation they deserve.
The WhittleCNC will ship anywhere in the world. For a wall plug specific to your country, simply specify the plug type in the order notes.
The WhittleCNC kit is easy to assemble, with fewer than 50 parts (not including screws and zip ties). If you have a Phillips head and scissors, you can be up and running in less than two hours.
