    Would it be possible to get a diagram of how we should be connecting a 2 wire PT100 to the v0.4 boards?

      I've updated the instructions at https://duet3d.com/wiki/Connecting_PT100_temperature_sensors#Duet_WiFi to clarify them. I'd add a photo, but my only PT100 board is inside my delta and using a 4-wire connection. I'm useless at doing diagrams except hand-drawn scrappy ones, so I'll leave that for someone else to add.

        "Each channel has a 4-position terminal block. We'll number the terminals 1, 2, 4 and 4 in order"

        dont you mean 1, 2, 3 and 4?

          Thanks, I've just corrected it.
