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

Design is the starting point

The design presented is made up of several components, mostly fashioned out of flat stock. Originally planned to be made out of 6.5mm plywood, your 4th axis structure will be fine with 6 mm (1/4”) plywood from your local hardware store. If you decide to make yours using the 3018, you can use the original design, but you will have to find exactly the same components the original demands. However, in my case, I was unable to find the same parts and I had to improvise. I was also concerned that the gears in the original design would not hold up to extended wear. Because I needed to experiment, I converted the design to STL files so that I could 3D-print the parts as part of my prototyping effort. To that end, I had to modify the design by uploading the SVG file provided to TinkerCAD and make my modifications there. Also, because I needed to do some quick prototyping, I 3D-printed my parts. Let’s start with what the original SVG file looks like...
