Apparently this CNC machine can be made in about 30 hours for approximately $100. It’s powered by an Arduino which interprets the code sent to it via Python. The Arduino then sends the data to the custom motor controllers that are based on the ATtiny 2313 and l298.

This is the second version of a homemade CNC machine build using mostly off the shelve parts. The first one aka “The beast” had a lot of precision issues due to play in most parts which in turn was caused by mostly bad cutting. Also one of the biggest problems was that when I have build it I did not think to allow later adjustments to be done. So this time almost every part of it allows for some adjustments. It is also easier to build due to the different design.
