Frostbot: CNC Cookie Frosting

[Brian Schmalz] sent in his Frostbot. It’s a fun CNC bot project that he built to frost cookies for his latest holiday party. He (wussed out a bit) and started with a kit based CNC machine, but he made up for it by driving it with his own control hardware (that sparkfun happens to have for sale). His USB bit wacker interface certainly looks interesting – I might consider adding it in front of the stepper controllers on my cnc mill. Especially interesting is the HPGL interpreter software that converts graphics to stepper commands via the bit whacker interface.

  1. You would have to flush the old color of frosting out of the dispenser every time you changed colors.
    I think it would be easier (and less wasteful) to just color-separate the image and then print each resulting halftone screen onto the cookie in cyan, magenta, yellow and black.

  2. You should use an screw type extruder for the icing to flow properly try to find an playdough type an design your own interface and tips and you will get much better results,also please get this machine FDA approved and you can sell it to bakeries. WCH
