      Hi All, I'm converting a Dremel 3D printer over to Duet control... it uses the Maker bot mechanical end stop switches v1.2 which are NO active low. I set up my config for this using the reprap configurator as suggested in the duet instructions. Everytime an end stop is triggered it caused my duet wifi connection to drop out. The board remains on, my Panel Due remains on but the connection is dropped. As soon as the end stop is released it comes back on. Any ideas what could be causing this?

        Odds are its wired wrong, shorting out 3.3v when asserted. Pictures?

          @doublec4 , see https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Makerbot_Mechanical_Endstop_v1_Num_2 for the correct way to connect those endstop switches to the Duet.

            Thanks, I had wired it based on that... or so I had thought... turns out I assumed common wiring convention of red = Vcc and black = GND was silly of me. Dremel does it backwards.
