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

Full CNC Workflow with Different Materials

We are ready to move forward with milling various materials beyond simple testing. It is important at this point to have our machines calibrated and able to accept G-Code on an ongoing basis. As mentioned several times before, the type of material and the nature of the shape dictate the settings and how well our cuts come out. For every project there will be common and specific settings, tweaks, and other attributes that may be unique to the material, the machine, or the project itself.

Here’s where we will focus our attention in this chapter:

  • Converting a non-CAD drawing into something your 3018 can process – a full workflow
  • Working with soft wood that requires a delicate touch since the resulting parts may be fragile
  • Working with soft metal, such as aluminum
  • Working with hardwood (our example will involve attempting to engrave/carve a piece of 2x4 or some similar material)
  • Understanding how to work...
