is it alive or dead

after search I find this diagram is it will work :
My power in 24 Vdc so the capacitive sensor NPN 24 v

blue for +
brown for -
black for signal

That diagram is good if your Duet is PCB revision 1.04. With earlier PCB revisions, we recommend using a diode as described in the wiki page con connecting z probes.

Actually brown is + and blue is ground (-)

yah I notes that but I was lazy to change the color
any way nothing will happen to capacitive sensor it's just will not function .

The diode goes the other way round.

That's better.

I have Receive the new control unit and I just connect with yat and put old sd card and all setting work fine
also I connect the capacitive sensor and it's work perfect

but still have issue with the screen

note : can you please put this diagram in you web site so if any one has same capacitive sensor NPN can find some data and not make my mistake !*

Thanks for the diagram. I've added it to the wiki page.
