CNC Plotter/Engraver: The Big Picture

Overview

For our final project in the embedded systems class we decided to take on creating a laser engraver controlled by user input through a joystick. To do this we first decided what would be needed to hold all of the equipment required to make the engraver work. We decided to create a wooden structure with a dual rail system. This rail system would then allow us to move our laser on the X and Y axis. We then attached a 3 stage stepper motor to the sliding board that would hold our workspace and a band to a stepper motor on the top rail which would guide the laser back and forth.
