Craig,
Your response prompted me to revisit the user manual... The BOB has one red LED next to the power input. It also has a green LED next to the output pins (2-9). Per the manual, "The power LED lights to indicate that the system is ready but disabled. When Status LED, (Green LED) lights, it indicates that the system is enabled". The green status light on my board is off.
The LED's do not change if I jog back and forth or play around with mach3...
I assume since the green LED isn't lighting, there isn't an output leaving the BOB and reaching the drivers? Or there isn't a signal reaching the BOB at all?
My apologies if my descriptions are hard to follow, I'm an accountant by trade, this stuff is pretty foreign to me.
Thanks for your help Craig.
