Here is a short video of a CNC hot wire foam cutter that is being controlled with an AtMega32u4 breakout board. It was programmed using the Arduino IDE by pressing the reset button and clicking on "upload" a second later. I have to make a few more videos providing details. I was surprised at how much the little thing could do; thanks for making such a fun little board.
