Here are a few fantastic videos from Lindsay Wilson showing what is possible with the AxiDraw beyond what the machine is intended for! You can read more about these projects, along with additional documentation, here.
I’ve been having great fun drawing stuff with my AxiDraw drawing machine and wanted to see what could be done with a small laser diode – either infrared for some laser cutting, or visible/UV for light painting. The modifications are pretty simple and the results are fantastic!
The hardware/code modifications described are equally applicable to other EiBotBoard-based machines, such as the Eggbot or Watercolorbot, and can obviously be used to control things other than laser diodes.
