That looks like a board I would not recommend look close to the white sockets near the axis outputs, it has series resistors for the driver optos, these of course are in the driver as well, this means half current through the opto and failure to work.
I was working with a free issue board where I met that problem before Dave Caroline ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
