My new project and the first results. Plotter! Arduino, software polargraph; plastic parts printed on a 3D printer, the rest – within 50-60 dollars total. The first prototype, made “on the fly,” I still haven’t sorted out the pen lifting/lowering properly, but the accuracy, finally, isn’t terrible like it was initially. Practically, this thing is ready to paint a wall without much modification.
A very interesting project, I will continue to improve it.
