Welcome to the forum, Glad you found us.
First things first I am sorry this is going to be a long-winded answer. Do you know if the CR touch is functioning? I know you had said that the probe deploys 2 times, does this happen on power up?
just a note you are troubleshooting this issue that the firmware denotes where the CR touch wires should go. You need to have firmware that is documented where the CR touch wiring goes. Sometimes it’s as simple as reversing the Black and White wire.
It will basically work like this, I will explain from BLtouch as it’s what I am most familiar with but I believe the CR touch is the same. If someone here knows differently please jump in.
There are 5 wires on a BLtouch, Brown, Yellow, Red, White and Black. Their purposes in the same order are Ground, Signal, V+, triggered output, Ground
Think about it as being 2 circuits in one device, the Brown, Yellow and Red are only responsible for deploying the pin and retracting the pin. that is their only function. The red and blue lights provide feedback as to what the BLtouch is doing but only to the effect of if the pin is in or out.
The triggered output and ground only trigger when the pin is being pushed by the bed and passes the hall effect sensor over a specific trigger point halfway up the BLtouch, (note this trigger point is located halfway in between deployed and stowed).
So that being said from your description it appears as though the digital side of the switch is working (yellow wire) but the trigger portion is not.
I would suspect that the firmware you have is meant to have the black and white wire plugged into a specific port or order and it’s just not seeing the “trigger” part of the BL.
Hope this helps. and hope to see you often
