Hey Sean, where did you wire the drive fault into the 7i77 Mesa board.
Mike, I apologize, I must have missed the notification there was a reply in the thread. Did you get this figured out yet? I have each of the fault outputs from the board going into one of the 7i77 24VDC capable inputs. It really doesn't matter which one. I have that input pin then set as a fault for the axis in the hal configuration (IIRC I did that in pncconf). I know that isn't real specific. I can go grab the configuration from the machine if it would help.
Sean
