(updated) I didn't like passing 230vac power to the front of the printer to switches, so I found another mains relay with a 6vdc coil (trips on 4.5vdc), Now I'm controlling the switching with low voltage, I think this option is safer and still functions.
Still asking Duet team for comments, specifically the SBC being powered connected via the default cable to an unpowered MB that is then powered up. Is this a problem?
