CNC Etch-a-Sketch
thingiverse
This project involved repurposing an old Etch-a-Sketch into a CNC machine by adding stepper motors controlled by L297+L298 drivers. The user won the Etch-a-Sketch in a Christmas gift exchange and decided to use Teacup Firmware, which features a built-in gcode interpreter, on an AT90USBKEY microcontroller. The machine is capable of moving at 8000mm/min, and the user plans to modify the gcode generator for more Etch-a-Sketch friendly output. The mounting plates were printed with the Etch-a-Sketch's contour in mind and attached using hot glue. NEMA 23 steppers were mounted to the plates along with large and small gears, ensuring proper alignment. A set of feet from Thingiverse was also added for stability. The project was controlled by standard gen3, gen5, or Pololu controllers, and tested with 2D gcode generated by Unicorn. A video showing the machine in action can be found on YouTube.
