There are 7 sets of step/dir/enable for external drivers on the expansion (5) and LCD_CONN (2) headers on the Duet. We have an expansion breakout board specifically designed to interface with large external drivers :

External drivers that do not need 5V logic will work connected directly to the Duet.

The information is available here on the wiki:

Only by installing a new driver chip. It's possible that connecting a small signal Schottky diode between the CS and SDO pads for that chip (cathode to CS) might also work, but I haven't tested it.

Thanks for the response. I will update my firmware and see if that fixes things.
