I have downloaded the demo version of Mach3. I have set up the address etc. I have leds on the outputs of the breakout board.
I can toggle these individually by playing with the active logic level and they work ok.
when I go into the diagnostic mode and use the jog command the dro changes as one would expect but the
signals to the stepper motors never change.
What going wrong?
thanks

Looks good John - that's exactly the same configuration as I am using.
You say you have the port address set correctly (0x378) I am wondering if your breakout board requires an 'enable' signal. What type are you using ?

Sorry to keep asking all these questions but what stepper driver board are you using ?.
Looking at the bob instructions as long as you have the JN1 &JN2 connected and 5Volt power applied you should be getting an output.
