Bltouch Duet2 WIFI crash

[Iker]

@dc42 I check all connections and normaly it's good and the BLTouch is new i receved it this friday and is official crealty BLTouch

[dc42]

@Iker your BLTouch is the Crealty version that uses nonstandard colours in the cable, therefore your wiring is wrong. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_connecting#bltouch.

[Iker]

@dc42 yes but i test all cable arrangement and isn't work

[dc42]

@Iker it's quite possible that connecting it incorrectly has damaged it.

[Iker]

@dc42 i know is the other version but the cable arrange doesn't work i think is damaged

[Iker]

@dc42 How can I be sure it's coming from the sensor?

[dc42]

@Iker the wiring to the Duet in your photo is clearly wrong for the Crealty versions of BLTouch. It's likely to be shorting out the 5V rail or feeding excessive voltage into the output on the expansion connector that you have connected the yellow wire to.

I suggest you correct the wiring to agree with the table in the documentation that I linked to.

@Iker It looks like your probe is wired like the 'other version', ie:

	GND (Left)	+5V (Left mid)	Control (Middle)	GND (Right mid)	Out (Right)
Genuine BLTouch	Brown	Red	Yellow	Black	White
Creality kit (other versions)	White	Black	Yellow	Red	Blue

So wire it:

Duet Z Probe connector pin	Duet expansion connector pin	BLTouch pin	Colour
IN		Out	Blue
GND		GND	Red or White
	5V (pin 1)	+5V	Black
	Heater3 (pin 8 )	Control	Yellow
	GND (pin 2)	GND	White or Red
