doesn't trigger, the pin also doesnt jump back into the retracted position. Notably, the z probe information on the web control never moves away from zero.
config looks fine regarding bltouch.
the z probe information only pulses once very quickly upon triggering with a bltouch. most of the time you will not see it in the ui.check the wiring for the z probe pin. a lot of users hard problems with the extension cable and the crimps of the bltouch.

I did continuity test and seems to be just fine
-
could it be a faulty BL touch?
-
I guess its a possibility. If the code is all correct, and i'm confident hardware is ok, then there aren't many other options.

that tells me there is a problem with your bltouch.
after issuing the deploy probe a small push on the pin should cause the bltouch to pull up the pin.
-
Looks like i'm going to have to try and get a replacement probe then. I feel like that's going to be easier said than done.
Feeling like this might be my first and last experience with BL touch...

i am using this as an alternative to the bltouch.

Please don't shot me if is not related but missing here your bed.g can you try to give a look here:
https://forum.duet3d.com/topic/10455/solved-bl-touch-deploy-only-one-time-with-2-03rc1If you have this in your bed.g:
M98 Pdeployprobe.g ;Try removing this as stated in that link.

@giostark
any help that people are trying to give is appreciated.
we are here to learn from each other.he stated that
When I send G30 the probe deploys but pin contact doesn't trigger, the pin also doesnt jump back into the retracted position.
the G30 command however does not execute the bed.g file.
The G32 command executes the bed.g.

Flipped over the two pins that go to the Z probe header and now it works. Bit odd because i'm sure it was wired correctly.

Glad to hear it's working.
But clearly it wasn't wired correctly and is now
