Denford Software & Machines

Hi I have purchased a new 5 axis BOB.

I am converting a Denford microrouter to run MACH3,
I have purchased a break out board but it did not have indipendant GND conections for the stepper drivers.
I have at the moment conected them all to the GND where the 12-24 v goes.
Has any one had the same issues.

Got it working.
I have put them all in the gnd at the 12-24 v gnd pin.
It does work but I do wonder if I should put them in the PC-GND pin
