I am a retired engineer /physicist mainly interested in microprocessor development. I have always been fascinated with CNC machines and lately decided to build a CNC router. I started by studying step motor driver hardware and have some prototypes of my own design which I am presently debugging. I am working on a 3 axis CNC router with the intent of simplicity and easy construction. The design will use a gantry, be 24" by 30", use plastic linear bearings and 1/2-10 acme drive screws. A website is in the works which will include this CNC design, as well as, microprocessor development techniques.

Hi there and welcome to the site. Always interested in home designed stepper drivers, despite the wealth of commercial offerings now available at silly prices...
