Before running a G-code setup on expensive material test it on free PVC plate. Video describes how to cut and flatten thick water or sewer pipe to use as a milling or turning stock.

Solution to "twitchy" servo issue. Servo does not flutter, but moves unexpectedly when Arduino program loads. Problem is not in the Arduino code but in the LED pin output. Servo operates pneumatic wrench on automated power drawbar. Part of a larger automatic too changer project.

An approach to making an Arduino-based tachometer for a milling machine or almost any rotary machine. Shows the limitations of an induction-type sensor and the success with an infrared sensor.

DIY conversion of 3 different (Grizzly, Bridgeport, Sherline) milling machines to CNC.
