If anyone is curious, so far I’ve had good luck with this touch probe on my work’s Nomad3. Probe seems repeatable and was not too hard to get set up. I bought both a minixlr cable and the touch probe on Amazon (the probe is the PGFun variant, normally open).
The wiring (from the female minixlr connector’s frame of reference) is Pin1-GND, Pin2-5V, Pin3-Signal.
NOTE: this does need a 6mm ER11 collet, which you can also buy from the same seller as the probe; I tried it in the 1/4" collet (being careful to not overtightening it) with no luck.
