      I have all the motors driving in the correct direction but there not stopping when being activated. The led on the duet wifi is off when not activated then turns on when i activate a mechanical switch or the induction sensor but then the motors continue to drive. i have tried to reset to both active high and active low with no change. being new to this I now don't know what i'm doing wrong or if its possible that i wired it wrong or what i might need to add or subtract from my config.g this is for a Cartesian style machine

          LJ12A3-4-Z/BX NPN wired
          output to cathode, anode to E0 STP pin
          ground to ground
          power to vin
          think i got a bat43 diode but might have been a 1N4148 cant remember right now what one radio shack had in stock at the time and its heat shrinked at the time
