Finaly I got it working.
I took the Touch unter the microscope to see if there is anything with the solder connections. And there it was. A little part of the Signal wire did a short to the GND wire next to it (really no human could have seen this with his eyes). Seems like a bad soldering job. So signal pin always was pulled down to GND. Its working fine now. Thanks for the help guys
Setting up now all the rest. How do I need to name the mesh leveling macro for G29?

Right now I am setting the Touch up with the old board to see if it still works.
But the config is right yes? Becaus it says : "Z: at min stop, Z probe: not stopped"
And one more thing because I didn´t find something about this. Were do I need to home when I home with the probe? From Smoothie I am used to home at the first probe point.
And will the IR sensor be in stock soon? Might wanna try it out

I already checked polarity and wiring a few times…
What happens with the output of your Bltouch when it is in Alarm mode? I did read that it then has continuos Signal output so we should be able to measure some kind of voltage.
I also checked it with pushing the pin like 300 times up und the webinterface didn´t react once...
I only get a reading if I disconnect the output wires

This is the wiring.

The webinterface reads always 0. Except when pull the probe connector (black and white cable from Bl, GND and signal). And with M119 it tells me that: Z: at min stop, Z probe: not stopped
Maybe this helps. I have also conntacted Antclabs because after some more investigation this night I found out that there is no voltage between GND and Signal out. Even when it is in alarm mode. I did read it should send a continous signal when in alarm mode. Maybe some one who has a defenetly working Bl touch could also test this

Hello,

I have set up my Bl Touch like descriped in the wiki. So far everything works fine. I can manually deploy and retract the probe and if I click on Home Z (in the Web Interface) the Probe deploys and bed is moving up. So far perfect. But the probe does not trigger. I want to use it as probe and as Z endstop. I think it is something with the configuration. Because I am extremly new to Duet I am not so familliar with it (used smoothie bevore and bltouch worked).

config.g
; Endstops
M574 S0 ; Define active low and unused microswitches
M574 X1 Y1 Z1 S1 ; Define active high microswitches
M558 P5 X0 Y0 Z1 H3 F120 T6000 ; Set Z probe type to unmodulated, the axes for which it is used and the probe + travel speeds
G31 P50 X0 Y-64 Z1.15 ; Set Z probe trigger value, offset and trigger height
M557 X15:290 Y15:318 S20 ; Define mesh grid
M307 H3 A-1 C-1 D-1 ;

Would be very nice if someone could help me
