Steve,
Excellent observation but one I have experimented with and in fact I misstated in my post...the pin orientation on the the Lexium side is pin 3 Step and Pin 4 Direction....according to doc I then go pin 3 Direction and Pin 5 Step on the Pokeys...it's in both the diagram and on the board itself..I have the Lexiums IS=3,13,0 and IS=4,13,0 with FL=1...translated to Pin out 2A (Output) as Step pin A3, Dir pin A4 and Follow enabled.
Thanks!
