      I'm new at this when I say new I mean "like yesterday new". I have a question that might seem really dumb, but here goes. I have a Mini Differential IR Height Sensor and I'm wondering why does it have to be connected to the Z Probe pins on the Duet 2 wifi and not the Z Stop?

        Because it's a probe?

        Actually I think you can connect it to and endstop if you just wanted to use it as a simple endstop switch. But when it's working as an analogue probe to measure the distance to the bed I think there's something special about the probe sense pin that the endstop pin lacks.

          Mainly because RepRapFirmware treats a Z-probe (which is a device that can probe the bed at different XY positions) differently from a Z endstop (which is insensitive to the XY position of the print head). It's possible to have both.
