Overview of this book

Until recently, Computer Numerical Control (CNC) machines belonged to the realm of heavy industry, but as technology becomes cheaper and smaller, these machines now can be used in home workshops. It’s not easy to get started, though, but thanks to this guide, you’ll be ready to take on a variety of projects in no time. A Tinkerer’s Guide to CNC Basics contains everything you need to get set up at home with computer-controlled machining and fabrication. Sparing you the theory, this project-laden guide helps you learn by doing. Once you’ve got to grips with the principles of CNC and installed the 3018 Pro CNC machine, you’ll gradually move from simple projects such as basic engraving to more complex milling and machining techniques. You’ll even learn how to upgrade your machine to accomplish more sophisticated designs. The plethora of projects in this book will keep you busy and give you the practice you need to get started with your computerized workshop. By the end of the book, your computerized home workshop will be one step closer to realization, and your machining skills will be taken to the next level.

Chapter 11: Building a More Capable CNC Machine

The OX

I first encountered the OX CNC machine at my makerspace when one of the makers was offering pre-cut metal kits for it. I jumped on the opportunity after I had a chance to do a little research. The OX is an open source, heavier-duty machine that you can find on the OpenBuilds site at https://openbuilds.com/builds/ox-metal-cnc-router-mill.3681/. The Thingiverse site for this machine is at https://www.thingiverse.com/thing:1660320.

As machines go, this one cries out for ballscrews (or heavier-duty leadscrews) very loudly. It is large, heavy, and meant for serious work, such as milling harder materials. Mine has a half-horsepower table router motor as the spindle from DeWalt, but if you decide to build one of these, you can use whatever takes your fancy. If your 3018 is up for the job, use it to cut the carriage pieces for you, or grab the drawings and either hand-make them or send them out for fabrication. There are some parts that need to be 3D-printed, and the brackets holding...
