Creality CR Touch not triggering

droftarts

@texastanker Does this picture match your wiring?
Touch
Because the Red and Blue wires are switched compared to our CR Touch wiring image:

That would make your wiring:

PCB pinout (Left to Right)	Out	GND	Control	+5V	GND
Creality CR Touch (most common order seen)	Red	Blue	Yellow	Black	White

So your wiring to the Duet is incorrect, because you have the Red (Out) and White (GND) going to GND, while the Blue (GND) goes to io7.in. Swap the Blue and Red wires.

@droftarts Looks like that worked! Thank you so much.

Having trouble now homing Z. Not sure if it is related. I can get it to home Z if I manually deploy the probe with a M401 before I send a G30. But when I try using my homez.g file I get an error because the probe did not deploy. Here is my homez.g file:

G91 ; relative position
G1 Z9 F6000 S2 ; raise z by 9
G90 ; absolute position
G1 X136 Y149 F6000 ; go to first probe point
G30 ; probe the bed using z probe to find Z0
G1 Z15 F5000 ; raise z to 15

What am I missing?

Is this still your probe definition in your config.g?

M558 P9 C"io7.in" H5 F100 T6000 A5 B1

texastanker

@Phaedrux Yes it is.

Phaedrux

Does the probe do a self test with the pin when the printer is powered on?

M401 and M402 work to deploy and retract the pin, but G30 by itself won't?

Can you please send M122 and M98 P"config.g" in the gcode console in DWC and copy and paste the results here?

texastanker

@Phaedrux Self test works fine.
Both M401 and M402 work
G30 won't deploy the probe by itself.

Here are the results:

Can you update your firmware by running sudo apt update && sudo apt upgrade on the pi command line terminal?

texastanker

@Phaedrux It's going to be a while. I thought I backed up all my config files. I guess I backed up the wrong ones. I had to reimage my PI because I couldn't SSH to it. Now I am starting all over.

texastanker

@Phaedrux Not sure if it had to do with all the settings being redone or the firmware update but it is working now. Thank you!
