CNC Pen Plotter Using Arduino

The idea behind this project is to make a CNC machine which can draw images or pictures on surfaces which can be paper or anything. It uses three stepper motors as linear actuators on each axis X , Y & Z. While printing, the proper synchronization of this entire three axis i.e., stepper motors, is the most challenging task. At present the data to draw is given programmatically i.e., hardcoded in program in binary format. A bit touches the surface & prints the pixel for logic 1 and lifts up in air for logic 0 & actuator changes its position for next commands execution. As in the future plan, it can access the G-Code directly from supporting software like in scale. Presented plotter is a two-dimensional (2D) plotter.
