How to build a DIY CNC machine completely from scratch. I designed the machine in Fusion 360 from the ground up and had a local water jet cut the parts.
The frame is built from 1/2" aluminum plate. Fully supported linear rails reduce the flex and NEMA 23 stepper motors drive the anti-backlash ball screws for the best possible performance on a budget. I used a TinyG motor controller in this project.
In this episode I put together the frame and Y axis linear rails so I can see if this machine is even going to work.
