A while ago I started working on a CNC machine (milling machine or 3d plotter), something very simple, very cheap, something that can be built with the stuff you find at local stores, without using very expensive and complicated parts.

The frame of the machine is build from wood and use furniture rails as guides for the moving parts. The stepper motors are from old printers on floppy disk units and they are very different one from each other. The driver motor drivers are build by me from scratch using L298n (i'll ost about the driver later) and a pic micro controller to command the driver (i'll also post about that later).

I'll just post a video with the x axis working and detail each part in later posts.
