• 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.

  • administrators

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