Creality CR Touch not triggering
-
I have tried everything I can think of to get this to work. I have even purchased a new CR Touch.
This is my first time trying to configure a board of any kind. I figured I had made some mistakes.
I have a Duet 3 6HC and a Creality CR Touch. Both are brand new.
The Touch does its self-test when powered up. It will deploy and retract using M401 and M402.
It just doesn't trigger when the probe hits the bed.Here is my config file and pictures of my wiring:

Check to make sure your wires are in the right place and that the crimps are good and that you're getting continuity end to end with a multimeter.

@Phaedrux The colors for the CR Touch don't map the same as the BL Touch in that document. For example, the BL Touch white is out, and for the CR Touch white is ground. It took a lot of trial and error to figure out the mapping for the CR Touch. I will check the wire connections again but if I have them mapped wrong it would be great if someone would tell me the correct order because the document does not tell you the mapping to the pins for the CR Touch. Since M401 and M402 work I had assumed the problem was in the config file. Any help would be greatly appreciated.

@Phaedrux said in Creality CR Touch not triggering:
cr-touch-wire-colours
Did you look at the CR touch portion? Is your CR touch different?
Based on the colors in there it would be the yellow wire sending the trigger signal.
-
@Phaedrux Mine are the same as in the picture but the table that shows the mapping to the board pins is for the BL Touch only. They don't have a column for the CR Touch. So, I had to guess by mapping to the CR Touch OUT to the Board IN, CR Touch Control to the Board OUT, Ground to Ground, and Power to Power.
-
@texastanker Does this picture match your wiring?
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 15What am I missing?
-
Is this still your probe definition in your config.g?
M558 P9 C"io7.in" H5 F100 T6000 A5 B1 -
@Phaedrux Yes it is.
-
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?
-
@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 upgradeon the pi command line terminal? -
@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.
-
@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!
