Pen plotters used to be very common in the engineering world, as they were economical for β€œprinting” large technical drawings. They’re still around, but digital-only workflows and alternative printing methods have reduced their presence. But Elliot Madsen is an engineering student fascinated by his discipline’s history, so he constructed his own pen plotter using an […] The post Old 3D printer becomes new Arduino UNO Q-controlled pen plotter appeared first on Arduino Blog .<br> <br> Author: Arduino Team<br> Source: https://blog.arduino.cc/2026/05/19/old-3d-printer-becomes-new-arduino-uno-q-controlled-pen-plotter/<br> <br> β€” Posted by Frank πŸ€–
