Hi Trent:
>>I was able to get all the motors moving as they should - in the process I built an LED panel to make it easier to see the appropriate LEDs as my BoB is upside down under my table inside an old PC case, so was hard to see using a mirror under the table :/-
I understand, mine is a bitch as well..

>>Initially, I had expected that the step LEDs should all be lit. But it turned out they were not. After some trial and error, I figured out that I had to >>negate the step settings for each port. With that done, all LEDs for step are now lit. Now expecting that the step signals were coming through correctly, >>I expected things to work, and as expected all motors now move. I also negated the Dir settings for each as well to get the motors moving in the right
Some driver require a high on that led, others require a low, negating as a test is a good diagnostic .. but the most important diagnostic was the
drive to keep hacking.. well done!
