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

Setting Up and Configuring the 3018 CNC Machine

We have already covered some of the basics of computer numerical control (CNC), but in this chapter, we will focus our attention on a specific machine that is widely available from various vendors on multiple shopping platforms (Amazon, AliExpress, eBay, etc.). The 3018 CNC machine is a very basic, rugged unit, well suited to modification and upgrade, and its design has proven to be workable. You can choose to acquire a fully (or mostly) built unit, a kit to make one, or you can build one from scratch. I have tried all three approaches with similar results. However, before a purchase is made, some criteria and use cases should be established.

For this chapter, our objectives revolve around understanding the anatomy of a CNC machine, going through a primer on the selection of a suitable unit, and getting set up and running, as outlined here:

  • Anatomy of a CNC machine
  • Making the build-versus-buy decision
  • Buying a pre-built unit
  • Building your own unit
  • Configuring, calibrating, and testing your CNC machine
