is it alive or dead

[yaman]

Hi every on
Recently I try to add z prope ( capacitive sensor NPN 24 v )
so as I know the controller max in 5V
so I put Converter Adjustable from 24 VDc to about 4.2 Vdc

I take the power from power supply and I connect the signal to capacitive sensor ( I'm sure the power in about 4.2 Vdc )
and I connect the signal to Converter Adjustable to about 4.2 VCD

the pin I put
GND to GND
4.2 Vdc to Z probe in

so just when I turn on the screen go to white and wifi LCD not turn on

I try to puch erase but nothing happen
so is my duet is it alive or dead
please help !!!!!!
I just need to know is it still function ?

An NPN output sensor switches the ground wire of the output. So you can't use a buck converter like that to convert the output to a ground-referenced voltage suitable for feeding into the Z probe input or an endstop input. The correct way to connect an NPN-output sensor to a Duet is described in the wiki page on connecting Z probes.

It's not clear to me from your photos how you connected the capacitive sensor, buck regulator and Duet together, so I can't say what damage may have been done. If you provide close-up photos of the connection to the Duet and the connection to the capacitive sensor then I may be able to provide further advice.

Looks like the main processor is OK but not the WiFi module. You could try re-installing the WiFi firmware.

@dc42
can you tell me how ?

[dc42]

If the wifi firmware is already on the SD card, sending M997 S1 will install it.

Set the line ending in YAT to LF only (in the Text Settings), then you will be able to read the responses more easily.

You didn't set the line ending in YAT to LF Only, so the response to M997 S1 was truncated, and I can't tell whether the firmware update succeeded or not.

truncated

@yaman, you still haven't set the YAT line ending properly. Go to Terminal, Settings, Text Settings, EOL Sequence.
