Description

The DIY writing machine is a functional device designed and built using discarded materials, including non-working DVD drives, waste wood, and old electronic components. It operates in the XY plane, mimicking the movement of CNC machines to perform automated writing and drawing tasks with high precision.

The machine’s design leverages the stepper motors and linear rails from two DVD drives to create motion along the X and Y axes. A fabricated pen holder mechanism allows vertical control for precise writing engagement with the surface. The system is powered by an Arduino microcontroller, which coordinates the stepper motors through motor driver modules using G-code programming for accuracy and flexibility.

This innovative device can produce clear and legible writing, draw patterns, and handle various writing instruments such as pens, pencils, and markers. Its smooth movement and reliability make it suitable for applications like automated signatures, basic CNC plotting, and educational demonstrations of motion control.

The project highlights sustainable engineering by repurposing e-waste and showcases practical skills in robotics, automation, and mechanical design. Potential future upgrades, such as integrating a Z-axis for enhanced pen control, could further expand its capabilities.
