the SIMPLEST cnc DRAWING MACHINE you can build | DIY 3D printed arduino CNC drawing robot

in this video I will show you how to build a new CNC 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 works on polar coordinates instead of cartesian, but don't worry, I will explain how to properly use it in my next video.
