I reckon its just something we are overlooking with the MB02V6 boards, as I can get, and have got the darn things running with the other boards, as you well know.
Peter,
Should have added on earlier post Pin 16 is connect to Sig on the DC03 and Pin 8 is to RL1 pin 9 to RL2.
5v and 0v come from the BOB as per drawings and the BOB has its own seperate 5v power supply.

Spent the weekend doing kids sport. OK a couple of things.
In EN012V3, the MB-02 is set up for positive logic on outputs 1,14,16,17(JP4) and negative logic on pins 2-9 (JP7).
In EN012V3, the DC-03 is set up for positive logic (JP2)
Since you are driving the two relays from pins 8 and 9 which are set up for negative logic, I'd suggest using negative logic for the DC-03 as well. So,
1. On the MB-02 change the jumper on JP7 to the 5V end.
2. On the DC-03 change JP2 end with the v pointing arrow.
3 on the Mach3 outputs tab, tick the active low column for output 1 and output 2.
4.on the motor outputs tab tick the active low for the spindle tab
Also in your motor outputs you have pin 1 controlled by your spindle dir output. What is pin 1 actually connected to? If it's not connected to anything then that's fine, otherwise set the port for Spindle dir to port 0 as your not using it.
Once you have set that up tellme what the DC-03 relay leds are doing?
Cheers,
Peter.
