Polar Drawing Machine - Vector Plotting test. - YouTube David Bynoe

I finally bit the bullet and got vector plotting programed into drawing machine. I ended up using the Geomerative processing library to load and convert an SVG, it has a polygonize function that makes it fairly easy. Each segments start and end points were converted to polar coordinates and sent to the machine. At larger length segments I do get a step pattern as one axis moves faster than the other, but I can get around this by making the steps really tiny and waiting till both axis have hit their target, any remaining jitter is mostly covered up by the bleed from the felt marker. If I switch to a ball point I can make the line segments as small as a tenth of a millimeter. Draw order is controlled by the layer order of the SVG in Illustrator. I still have to work out how to make one end of the line a start, as a few of the words are drawn backwards in this test. Oh, if you haven't guessed it, the formulas are for the conversion between cartesian to polar coordinates and back again.
