TL;DR
Elliot Madsen, an engineering student, has transformed an old 3D printer into a pen plotter using an Arduino UNO Q. Pen plotters are devices that move a pen across paper in the X and Y axes, making them ideal for producing large technical drawings. Madsen utilized parts from the 3D printer, including stepper motors and aluminum extrusions, and implemented a CoreXY motion system with a solenoid to lift the pen. He also designed a vacuum table that uses fans to hold the paper in place, eliminating the need for clamps.
Why This Was Curated
This article presents a practical project that combines software and hardware by repurposing an old 3D printer into a pen plotter using Arduino, making it highly relevant for software developers learning about embedded systems. The content is accessible and offers actionable insights, though it could benefit from more detailed instructions or resources.
