Art,
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 :/-
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 direction.
Glad the world can't see into my shop, as I had to do the happy dance for just a brief moment. Now to limits and homing, and then on proper motor timing. Maybe some saw dust after that.
Thanks again for the advice and encouragement Art.
