Arduino Mini CNC Plotter Machine from DVD drives


An instructables on how to make anĀ Arduino based mini CNC plotterĀ from old DVD drives by Ardumotive_com:

For the X and Y axes we will use two stepper motors and rails from dvd/cd drives and for the Z axis we will use a small servo motor that moves the pen up and down. For the mounting base we will use a small piece of plexiglass.
You can easily attach a pen (or pencil) – irrespective of its thickness – on it. I tried to use an extension of cutting tool (e.g.Dremel) to engrave materials with no success. So this mini cnc can only be used as a small plotter and not as an engraver machine.
The Arduino-based circuit is using the ATmega328 microcontroller, two L293 motor driver ICs and an usb to serial module. You can easily make it with the Arduino uno board and an breadboard.

  1. Neat – now make a mahogany-enclosed one with some extra gold plating, slap on fingerprint reader module for authentication (regardless of how bad an idea that generally is anyway) and start selling it at iphone-level prices as an executive-level robo-signature toy.
