6-30v capacitive sensor

The new P5 probe type is already implemented in the 1.14 firmware release.

oh nice.
I just tried it but it still doesn't works
M558 P5 X0 Y0 Z1 S0 (s0 since the sensor is open by default)
If I do m119 I get 'at min stop' when the sensor isn't triggered and 'stopped' when triggered but doesn't stop Z motion
any hint ?
Thanks

S0 doesn't work on M558 at present, so a type 5 Z probe needs to have an active high output.
Is your sensor PNP or NPN output?

David,
The bad type I guess. so in the moment I don't have the choice to use the E0 stop pins . Any input how I can that working with what I've right now ? I cannot get E0 stop triggered at all. I think it's a voltage/led issue. I even tried to feed the pin with 4.02 volt and the led wasn't bright as the other end stop leds -
I can't help unless you tell me what sort of output it has.

David,
it's a normally open sensor so the logic must be inverted, it looks like that:http://www.aliexpress.com/item/LJC12A3-H-Z-BX-DC-6-36V-1-5mm-Distance-Capacitive-Proximity-Sensor-Switch/1726079980.htmlit's connected on 12v and I was lowering the output voltage using some resistors to bring it at 3.24v to use it on Z endstop pin on the ramps

According to http://www.mikrocontroller.net/attachment/279364/Condutive_Proximity_Switch_Series.pdf the /BX ones are NPN output and the /BY are PNP output. So if it is a /BX type then instead of resistors, you should use a small signal Schottky diode, connected cathode to sensor output and anode to the STP pin on the E0 endstop connector. A silicon diode such as 1N4148 may work as well, but although that seems to work for some people, the last person I suggested it to found that it pulled the E0 STP pin low enough to light the LED on the Duet at less than full brightness, but not low enough for the Duet to recognise it as triggered.

Thanks David, it works perfectly with the 1N4148 diode. I was able to got that one at a local store near here.

I'm glad it worked for you. I'm in the process of completing the documentation pages at https://duet3d.com/wiki/Duet_Wifi_Wiki. I've done the page on endstops, I'm currently doing the page on thermistors, and I'll eventually do the page on Z probes.

I have now documented how to connect several different sorts of Z probe at https://duet3d.com/wiki/Connecting_a_Z_probe.
