I think you found the root of your problem in your other DWC tool thread?

config is for RRF3, but only RRF2 is installed.

@phaedrux Just spotted another problem, looking at the picture above, looks like he is plugged into the wrong port.......
@PRIOR123 Check the wiring!!!!!

@paulhew I don’t think the wiring is wrong. Red, brown and yellow look correct on expansion port, and white and black look correct on probe input, though perspective makes it look a bit like it’s on the PanelDue pins.

More likely is that the config is for RRF 3, but RRF 2 is installed. @PRIOR123 is you are on RRF 3, please post deployprobe.g and retractprobe.g.
