Before i blow my board . 3d touch help

Definitely looks like an older style probe.
Did it include any instructions on where it suggests you use the resistor?
-
came with no paperwork :{
-
does the 240 ohm sit on the black wire ?
-
From what I can tell from googling this is it maybe? http://www.geeetech.com/wiki/index.php/3DTouch_Auto_Leveling_Sensor#Electrical
It definitely says it comes with a 10k resistor, but the instructions don't mention anything about it and only over connecting to ramps.

i think its to connect a led to the white black wire for debugging

From the Duet BLTouch documentation:
https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch
For all Duet 2 WiFi/Ethernet boards prior to version 1.04
If you have the older BLTouch, also connect the 240 ohm resistor between Probe GND and Probe IN. On the newer BLTouch, cut the PCB trace on the BLTouch to reduce the output to 3.3V as described in the BLTouch instructions.The Z probe input on the Duet 2 Maestro and Duet 2 WiFi/Ethernet rev 1.04 and later is 30V tolerant, so it doesn't matter whether you reduce the output of the BLTouch to 3.3V or leave it at 5V.

like this ?

That looks correct.

@phaedrux ok thanks for your help :}

Hi @richard-f did it work with 10K resistor? and did you connect it between black and white wire?
