And you can download a pre-hacked version based on wheezy that can run machinery with sub-micron accuracy, far better than the average machine can do, as its subject to thermals etc that limit it to perhaps a thousandth of an inch in everyday use. From linuxcnc.org today and everyday. Free every day. I have 4 copies of it running here. On the right board and cpu, this software can send a step pulse to a stepper motor driver every 25 microseconds. Thats 40 kilohertz, not the stepper motors top speed, so if you really want to move fast, a 90 dollar card can take you to the limits of the opto-isolaters in those drivers at somewhere above 200 kilohertz. Using that card allows one to be a whole lot less picky about the board and cpu. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
