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.

Technical requirements

In this section, we are going to use several tools. You are not constrained to these tools specifically, but the idea is to apply what is out there to your needs. I generally like to have the following:

  • Something that will convert an image to a vector graphic. This helps me make use of hand-drawn or scanned images that I would otherwise have to re-work. You would need to gauge whether the amount of re-work you must do is worth the effort or whether it is better to just redraw an object. I particularly use this kind of tool whenever dimensions are in short supply, or the scale is not clear or workable. For my BD-1 project, the drawing arrived scanned but also with some smudging on the lines.
  • If you work with CNC, you will eventually have to learn how to use CAD to either create or change existing drawings. There are several free applications out there. I primarily use TinkerCAD, but there are others (free and not free), such as FreeCAD, Fusion 360...
