CNC Router

In middle school, I really wanted to build my own electric guitar. Months of binge watching manufacturing videos on YouTube led me to the decision that I wanted to cut one on a CNC router. Off-the-shelf CNC routers were prohibitively expensive though, so I built this one myself based off the PrintNC open source design in 10th grade.

I did deviate from the common design in a few places, for instance by modifying a 3D printer controller to add CNC features. It uses commonly available steel tubes, 3D printed parts, and a surprisingly precise AliExpress spindle, ball screws, and linear rails.

I used it to machine tons of robot parts. It taught me so much about material science, precision, and how to make things real.
