It sounds like a wiring issue. The probe is getting power and ground, but no signal. Triple check your wiring and crimps. A good test is to connect the short leads from the BLtouch directly to the board to eliminate the extension wires.

I saw this settings made in the configuration tool. I tried to change the settings manual. Maybe I made somethig wrong there?

That all looks ok as long as you're actually wired up to the io7 in and out pins.

dutti

@Phaedrux
ok. I´ll check everything-

dutti

@Phaedrux
What do you mean with ´´actually wired up to the ioin and out pins´´?

Phaedrux

I mean that your config looks ok, now the wiring must be correct for the config to work.

dutti

@Phaedrux
ok sry.
I tested the wiring. Its not the problem....
this is the last problem I have to solve before starting. Thats really bad.

Phaedrux

If that's the case and the wiring is good please update your firmware (as linked above for the Duet + SBC). Send M115 after to verify.

Then please send M98 Pconfig.g and report any errors.

dutti

@Phaedrux
M98 Error: Non-empty string expected
firmware is updated

Phaedrux

That's a weird error. You're sending this exactly?

M98 Pconfig.g

yes

Phaedrux

try M98 P"config.g"

´´´Response to long, see console´´.
I havent connected the expansion board, yet. Is this a problem?

Phaedrux

Are you in the DWC gcode console when you send that?

dutti

@Phaedrux yes

dutti

I homed z again. It's homing without triggering manual the BL.

Also when I go down with the z axis... doesn't care which amount and then homing z, the z motors are turning back always the same amount and it stops.
--> I hope that helps

Phaedrux

I'm not exactly sure what you mean.

Looking back over your config.g I notice two things on your M558 command that we can try changing.

M558 P9 C"^io7.in" H15 F120 1400

First, you're missing the T in front of the 1400 to define the travel speed between probe points.

Second, try removing the ^ from in front of io7.in. I think it's only zprobe.in that requires the pullup.

I'd still like to see what the gcode console output is from sending M98 P"config.g" It should echo SOMETHING back.

dutti

M558 P9 C"io7.in" H15 F120 T1400 ----> doesn´t work

M98 P"config.g"
--> response to long, see console

Should I buy a other sensor?
My motivation after a few days is down.....
