I did not buy the wiring loom of the TC kit (I think it's more fun to do it myself, and I have a different layout of my electronics panel). According to the Config.sys on Github I could figure out most of the TC wiring. I do have a question about the Z-stop. According to this line it goes on the Z-endstop connector: Code: M558 P7 X0 Y0 Z2 H3 F360 I0 T20000 ; Set Z probe type to switch, the axes for which it is used and the dive height + speeds But what pins do I use ? Is that GND and IN ? Do I need a pulldown resistor for that ? I did check the Duet dozuki, but documentation is not clear about this (or more possible, I overlooked it ).
