My friend Charles gave me an old CNC mill to try to resurrect a few months back and I've tried several different control systems to get it working again. Finally, after trying and failing over and over I've started working on using an Arduino to control the beast using
grbl. Also, a big thanks goes out to Shannon over at
www.spaceopera.org for his help all along the way.
The first step was to build a
simple circuit and test out my Arduino and driving a motor with a big easy motor driver (see picture). It's easy to control the direction of the motor by simply setting pin 8 high or low on the Arduino.
I now have a single axis working as a test. Now on to bigger and better things!
