My number one question is, does anyone have a suggestion of a good board that could handle stepping those 24v signals to control the step motors? I'll need at least 12 (and maybe as many as 18) 24v outputs appropriate for software stepping. The limit switches are wired separately to another plug on the Arc-station. I can not tell if there are any inputs carried through the 37 pin cable (but there might be a few).
There are also 6 other 24v outputs but I have not traced down exactly what they all are or if they are all used. (I suspect it is uni-polar1/2 stepping the 6 wire step-motors). One signal to each of 4 transistors on the driver board. I've done a little poking with a multi-meter and as best I can see the Arc-Station is sending 4 24v step signals for each step motor. The Arc-Station is connected to the driver board by a DB-37 parallel cable. It's controller is Gerber's "Arc Station" and an electrical box with the power supply and driver(s) runs off of Gerber's horrible yet very expensive ArtPath software. It is a small (about 3ft square) table top router. I am beginning a conversion of a Gerber Scientific Dimension 200 (D-200).
