KrisKasprzak is fairly prodigious in terms of Teensy-based output, so it was no surprise to see his Teensy-based motorized table saw fence project, complete with detailed pictures, video, and source code!
The CNC motorized system is compatible with Craftsman, Dewalt, and Rigid table saws, and features two NEMA-17 stepper motors with A4899 drivers, a 2.8″ LCD, and a Teensy 3.2. Simply enter your desired fence location, and the steppers do the rest.
A simple “garage-made” PCB ties it all together, though it could just as easily be breadboarded. The video below shows how to make your own, with source available on GitHub.
