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

Project: Building Your Own 4th Axis

Previously, we looked at a rotary axis for your 3018 that was commercially produced. However, we may want to create our own with its own particular features, including the ability to hold components much like you would on a lathe. Rather than depending on the symmetry of the object being machined so that it rotates evenly on rollers, you may want to work on parts that would otherwise not sit on a store-bought 4th axis in a stable fashion. An example might be a narrow cylinder shape, or one that doesn’t have a consistent diameter (such as a bottle). To that end, we will look at building such a unit for your 3018 based on work by ZenziWerken. You can have a look at his original design here: https://www.thingiverse.com/thing:2344975. In this chapter, we will look at the design and update it as necessary for our purposes.

As part of this project, we will develop a few skills and recycle what we have learned with the store-bought 4th axis:
