• EndStop

    Hi, I have 4 motors on the z axis and I need help to know how and on which pins a switch is connected on each motor, I have simple microswitches and I use the Wi-Fi duo v1.04, I need to know if I have to add pull up resistors to be able to adjust the microswitches in case you have to directly use the entries at the end of the extension header.

    I don't really understand what you're asking, but have you seen this? https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches

  • On the x,y,z,e0 and e1 there are physical pull up (and series) resistors, so presubably you have to bring your own when using the expansion header without the expansion board.

    There are weak pull up resistors built in to the microcontroller, but I recommend you add external ones.
