    My recent fascination with electronics has invariably led me to CNC.
    I am putting this together as a proof of concept. I have not decided what software I am going to use yet. Besides, what fun is the software without the electronics and a mechanism to move and make some noise?

    Here I have a rough draft of the x-axis

    ...Constructed from aluminum angle and square tubing. 18" x 18"
    ...The L shaped brackets were extra parts for some metal shelves I recently bought.
    ...The ball screw is 1/4" x 20 x 19" threaded rod.
    ...The stepper motor and gear I salvaged from an old scanner.

    For now it is connected to an Arduino motor controller.
    Video on that here.

    This project may consume me for some time and I will probably trash the whole thing and start over multiple times.

    To do:
    Build main chassis
    Square x-axis chassis
    Incorporate spacer/bearing assembly for ballscrew.
    Move ballscrew and gear to incorporate belt salvaged from the same scanner .
