the SIMPLEST cnc PEN PLOTTER | how to build it

in this video I will show you how to build a new high quality Arduino based CNC pen plotter I designed. it’s meant to be the simplest drawing robot you can build, in fact it is built only using some wire, a rubber band, some bearings, some cheap electronics, and a few 3d printed parts. this CNC pen plotter works on polar coordinates instead of cartesian, but don’t worry, I will explain how to properly use it in my next video. this CNC pen plotter is a great option if you want to get started with CNC pen plotters and Arduino, it’s very easy to build, simple to use and cheap. some useful links: - firmware and software (includes also a user manual): - 3D models: :4907608 - 28byj48 bipolar mod (go to minute 1:50): images used in this video - panda: - world map: music:
