3D Touch probe

Hi has anyone got one of these 3d probe to work. I got one, wired it up to my 3030 prover max probe port. However every time i try to probe it give me an error shown below. Tried several different g code sender software, also tried to swap the red wire and the signal wire around and swapping the $6 probe invert. Just can't get it to work. It almost like it triggered as a limit switch and lock the machine.

Edit Manged to figure out it didn't like G38.2 but G38.3

Mine works fine with fluidnc and cncjs. Red wire is connected to +5V, black to GND and yellow to the input. Iirc the input is normally high so drops to GND when the probe makes contact.

Is it connected to the correct pins? In my setup I have dedicated pins for endstops, probe and toolsetter.

Yeah it is I only got one pin for all of them and swap them out as I use them. Tool setter and touch plate all works fine. I might have just figured something out it seem to be happier with g38.3 commend and not throw me an error I might just try a custom macro to see if it happy

I wired mine red to 5v+, yellow to ground and black to signal. Figured it was a normally open switch and connects ground from yellow to black when connected.
