I have come across a couple of stepper controller boxes on Ebay and was wondering if they are worth pursuing. They are of a micro steppping type but they have a rs232 input. I know that all the other controllers connect into the parallel printer port. Is this something I should avoid or go after. I want to be able to use a "standard" cad/cam program and avoid some kind of specialty program to make these boxes work, or would an adapter board to go from parallel to serial work. Comments.
If it's not nailed down, it's mine.
If I can pry it loose, it's not nailed down.
