Probably only the step-dir drives. And many of those that do want to see the encoder also pass-through the encode signal for use by the controller. > Even worse, I bought a 7i77 > card to host a set of super fancy Omron drivers once upon a time and know I > don't even understand how I was thinking when I bought them.

You would need a 7i74, yes, to connect to the (presumably) 5i25 that you have. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
