TL;DR
This article covers a unique DIY pen plotter created by András Vujovits that utilizes delta kinematics instead of the more common Cartesian movement. Delta kinematics employs two parallel arm linkages that allow for precise positioning by moving carriages relative to one another, enabling the pen plotter to draw anywhere within its defined workspace with some clever math.
Why This Was Curated
This article presents a unique DIY project that combines software and hardware concepts, making it highly relevant for software developers interested in embedded systems. It provides actionable insights into building a pen plotter with delta kinematics and a tool changer, though it could benefit from more detailed tutorials or step-by-step instructions.
