DIY Pen Plotter Uses Delta Kinematics and a Tool Changer
Arduino Blog
EDITOR BRIEF
This DIY pen plotter is different from typical Cartesian designs because it uses delta kinematics, with two linked arms and carriage motion to place the pen. It also includes a tool changer for swapping pens or markers, plus a paper feed that advances fresh paper across the bed. The builder made software that turns images into toolpaths and G-code for the machine.
INSIGHTS
This is a good example of how mechanical design changes software needs: unusual motion systems need custom code. If you're learning, try comparing Cartesian vs. delta kinematics and then practice generating G-code from a simple image.
