Gregg, This isn’t exactly what you were asking for, but it might work. CRAMPS-BOB3-a3 <https://oshpark.com/shared_projects/2p1xADDj> It is for the CRAMPS board. Instead of the step/dir/common pins going to a Polulu board, the are shipped over to the output connector on the CRAMPS board. So you can use the pin header to run on off board drive. If you are interested I can send you the schematic for the board. If the link above doesn’t work, here is the URL <https://oshpark.com/shared_projects/2p1xADDj>
