2012 DSP - Stepper driver connection

[dwessels]

Hi,

I am trying to get the new 2012 DSP wired in to replace my old DSP.
I am using Bart's 4 axis board. http://www.buildlog.net/documents/A40005_rev_1.pdf

The old DSP was connected with to the stepper driver with GND, Pulse+, Step+.

The new DSP does not have a GND pin for the stepper driver, it only has DC5V, Step, Dir.

What is the correct way to wire the two together?

Thanks

Ground is ground - get it someplace else on the board - likely the case itself is grounded, so you could use that.
