Kotrljko is a drawing XY machine that I created a few years ago with the help of my partner. It was one of my first attempts at hardware projects and it was a challenging journey. However, in the end, Kotrljko successfully creates drawings.From a technical perspective, Kotrljko uses two Nema17 motors, Arduino shields with controllers, and wooden and metal parts that were handmade by my partner. On the software side, I utilized the Universal Gcode sender and Inkspace program with an addon.
