Hi John, I used an oscilloscope to look at the pin and nothing was coming out. Looking at the hal file, it looks like stepconf didn't connect the charge pump to the e-stop. I'll do some more testing once I get Ubuntu installed on my CF card. Running off the CD is a bit of a pain.
The exact frequency isn't critical. My circuit should trigger on anything above about 200Hz. Outputting step pulses on that pin was enough to trigger it.
