Hi all -

Since I don't do facebook or other social media, I figured this was the best place to post this.

I did the EH 8-step mod that defeats the step signal when sequencing is stopped.  There is a critical error in the DEFX documentation in that the +3v and Ground signals to be connected to the relay are reversed on the main board.  It was an easy fix to reverse them once I realized the problem and it's working great now!

P.S. for anyone doing this mod - the documentation isn't kidding when it says that the switches and jack wiring is very frail.  I had to reconnect three of them in the process of doing the mod.
