BUILD A PLOTTER USING SCRAP DVD DRIVES




Building your own CNC machine can present a series of varied challenges. There are the software considerations, but also the mechanical side of things – motors, shafts, screws and slides all need to be addressed in a working design. Of course, you can always outsource some of the work – and that’s precisely what [Daniele Tartaglia] did  with this pen plotter build (Youtube link, embedded below).

The build gains X and Y axes by virtue of two salvaged DVD drives. The tray mechanisms come ready to go with stepper motors and lead screws already assembled, and make a great basis for a compact plotter. A wooden frame is constructed to hold everything together. The pen is held against the paper with a rubber band which helps the ballpoint to draw a nice dark line, with a servo used as a pen retract mechanism. An Arduino Uno with a stepper driver shield is then employed to run the show.

It’s a tidy build, with neat cable management and smart design choices giving it a pleasing aesthetic. The CNC fundamentals are good, too – with minimal backlash and slop, the plotter is able to draw quite effectively. Old optical drives are a popular choice for plotter buildsas it turns out.
