Well as far as I can tell right now, seems that everything is working. I didn't just plug it in and try it as you suggested, but that probably would have worked. At any rate, came back to it again today and everything was working magically. Maybe I just needed to shut everything down and fire it up again. The only thing I had to do is switch directions on a couple of the motors. Even the EStop is working correctly
Although, I do have a question about the EStop. As I said, it"s working, but differently than it did with the PDMX 411. Now when I hit the EStop, it shuts the motors down as it should...not locking them, but stopping any motion. But now it seems that Mach 4 is not aware of the EStop being pressed....the screen keeps updating as if it were still cutting as usual. I don't know that this is a problem, but it certainly is different than it was. I have the Estop on port1; pin 10. Is there something else I should do or is normal behavior (now)?
