DIY CNC Machine

Affordable & Accessible

Project Overview

This CNC Machine project targets individuals seeking a competitively priced, larger-scale CNC machine for their DIY needs. Many hobbyists and novice machinists find industrial machines prohibitively expensive. However, the reality is that, with a few minor trade-offs, you can construct your own CNC machine for a fraction of the cost. I meticulously designed this machine from the ground up using CAD, with the entire assembly process achievable using basic workshop tools, eliminating the need for welding. This approach empowers the project to have a more significant impact within the community, enabling others to follow suit.
