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
