      Hi
      I s it OK to wire directly Fan output on Duet wifi to Enstop input on other duet wifi in order to use it as a trigger on the second

        I don't think so. The fan output would be the voltage of the PSU and the endstop would be expecting much lower. It would only be safe to do if you could ensure the endstop is only getting a low voltage.

        I think the endstops are max 8v tolerant on recent revisions. Though I'd personally want to keep it to 3v as it would normally expect for an endstop.

            I don't understand what I'm looking at there.
