i'm trying to make a mivro/nano plotter/cnc that can be used for most of the parts you can find into dvd players like this http://www.instructables.com/id/Mini-CNC-Plotter-Arduino-Based/

in order to build this you'll need for the axis Ø 3 (from dvd and cd player) 2x80mm and 2x85mm one servomotor two screw motors (from cd or dvd player) some Ø3mm srews ans bolts and more ittle screw for fix the motors etc.... For the drive of the x and y axes, you will have to use a piece of wire roll around the 2 screws ;)

for the electronics parts i use one arduino nano and a motor shield

Leave a message if you want a version for smaller axes
