Re: EMC with intelligent stepper controllers

["Steve Carlisle" <quatsein-at-island.net>]

Okay, so what you want to do is build a front end program like
Flashcut, and send serial ASCII comands to the serial driven
SimpleStep boards. I know PicServo has front end software and
source available for download, I wonder if there is anything in it
that might help you. You can lookm here
