DIY Snap-Together Desktop CNC Milling Machine
The MTM Snap, so named because it’s part of the ‘Machines That Make’ project and it snaps together, is a project out of MIT’s Center for Bits and Atoms and the MTM Snap designer Jonathan Ward. With this machine, one can make pcbs or mill small 3d objects. I had originally used electronics from the class HOW TO MAKE ALMOST ANYTHING, but since these electronics have exposed copper they will begin to decay over time. As a result, I chose to utilize TinyG driver board for the electronics, which will wear better with age. One of my goals was to have a more robust board for the motor drivers and controller. I also wanted to tidy it up a bit, so I made the decision to add an under cabinet area where the power supply, cooling fan and safety switch are housed.

The TinyG project is a multi-axis motion control system. It is designed for CNC applications and other applications that require highly precise motion control. TinyG is meant to be a completely embedded solution for small/medium motor control. Here are some of the main features of the v8 hardware:
ChiliPeppr Hardware Fiddle makes it easier to bridge the gap between hardware restrictions and software needs. Getting access to hardware typically requires a serial port interface but the ChiliPeppr has a Serial Port JSON Server that solves that problem by creating a websocket bridge between your serial port and your browser. Once that is achieved, you are then able to manipulate the hardware from your browser using Javascript. .
