It's possible. You'll need to modify the firmware to lengthen the step pulse on time, and invert the enable line as explained in the wiki section on Sanguish firmware. As is, the step pulse is too short for these drivers. It's been done with other TB6560 boards but not yet as far as I know with Sanguish. Someday I'll get motivated and take a look at it and do some testing with Marlin.
