IR Sensor always triggered
-
your config has a mixture of rrf3 and rrf2 syntax. that does not work
which firmware version are you running?
-
Generating a new config file with https://configtool.reprapfirmware.org/ does not change the triggering problem. I am on the latest stable release 3.2.2 firmware

Heres my config.g for the same printer (bmvmgn cube?).
I'm on 3.2 and use the mini IR.

It looks like you've got to invert the probe input signal.
@nick9one1 has a "^" in his configuration and you do not.
-
I tried inverting and still shows always triggered. I took nick's ;endstops and ;z-probe and pasted them into mine but it did not fix the problem. new config.g attached
-
You did a power-cycle after updating config.g?
Can you use M119 a few times with it triggered and not triggered to make sure it's functioning properly?
-
Problem was a bad crimp on the out/in pin at the board. I started re-crimping each wire and it worked after re-crimping it.

@alankilian @nick9one1 @zak062
FYI "^" is for the pull-up resistor, "!" is used to invert input. You shouldn’t need either with IR Probe. The configuration tool does not output either for IR probe. See https://duet3d.dozuki.com/Wiki/Gcode#Section_M558_in_RepRapFirmware_Num_3Invert the input by prefixing the input pin (C parameter) with ! character, when using an NPN output inductive or capacitive sensor or using an NO switch (not recommended, use a NC switch instead).
The pullup resistor on the Z probe input is disabled by default. Enable it by prefixing the input pin (C parameter) with the ^ character. Enable pullup resistor with ^ if using Duet 2, running RRF3, using the Z probe input pin, and the probe type is a switch or BLTouch.

Thanks @ian !

I do appreciate everyone's help/input. Now on to wiring the rest of the board
