Build a homemade motorized table saw fence and get faster table saw setups for cross cut or rips on your Craftsman, Dewalt, or Rigid table saw. This CNC motorized fence controller or PLC controller is based on a Teensy 3.2, a 2.8" TFT LCD, an d2 NEMA-17 stepper motors with A4899 stepper drivers. Unlike CNC controllers where G-code is needed, you simply enter the desired fence location, and the steppers slew to the correct distance. This electronic project was created using garage-made PCB boards, but components could be soldered to a breadboards. The link below includes free source code, and the parts list is in the description. It's a perfect project for woodworkers, hobbyists or DIY'es.
