This is my wiki for my 3-Axis CNC machine build

My goal is to have a complete documentation behind the principles that went behind the design of my 3-Axis CNC machine.

There isn't a lot of content right now since I made this wiki not long ago. Stay tuned!

The purpose of this page is to describe the overall design process for my 3 axis CNC machine, which hopefully should be helpful for 3-axis CNC designs in general.

Feel free to contact me with any questions and I'll get back to you:
