IR sensor Z probe on RRF3 config issues
Hello, I connected the DC42 IR sensor to my board using the Z0 endstop connector, and I can see that electronically the power (3V3) and connection is good (in standby the status led of the sensor is on, when I put something nearby the sensor the led goes off, also, the led on the motherboard has the inverted state of the led on the probe).
The issue remains with the config file, in which I have the following lines:
; Endstops M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop M574 Z1 S2 ; Z-Probe M574 Z0 P"nil" ; no Z endstop switch, free up Z endstop input M558 P1 C"zstop" H5 F120 T3000 ; Z probe connected to Z endstop input G31 P500 X0 Y0 Z2.5
And I can't seem to figure it out. On the first page under sensors I don't even have a "Probe" sensor. Also, if I run G31 in the console it returns:
Error: G31: Invalid Z probe index
Can you send M122 and M98 P"config.g" and post the results?
Also post the entire config.g.
Here is all the info, I did not know about M98, it seems very handy.

Error: Pin 'zstop' does not support mode analog read Error: Invalid Z probe index
There's our problem. You're going to need to use the Zprobe connector instead of the zstop connector.
With Duet 2 and earlier Duets: Connect the VCC, GND and OUT pins of the sensor to 3.3V, GND and IN respectively on the Z probe connector, and select mode 1 in the M558 command.
Your M558 command would then become
M558 P1 C"zprobe.in+zprobe.mod" H5 F120 T6000
M918 P1 E4 F2000000 ; configure direct-connect display
The direct connect LCD display of the Ender 3 will only work with the Duet Maestro, so that M918 is being ignored.
You can also remove this line
M574 Z0 P"nil" ; no Z endstop switch, free up Z endstop input
Okay that’s what I will do, move to the Z probe pin.
@alexic M918 is only supported on Duet Maestro, or in firmware 3.2.
@droftarts I am not using that comand, it was there from a configuration file example.
@Phaedrux It says that in the Gcode dictionary, I had to look it up!
@droftarts I am not using that comand, it was there from a configuration file example.
I was explaining the error message. But be careful when using someone else’s config, it won’t always suit your machine, and may cause problems. Make sure you understand every command, and use the Gcode dictionary to help you.
