Z-probe always gives open in M119 command whatever the probe is on or off August 29, 2021 04:13PM |

Good evening
I am having some problems with installing a new inductive sensor as a z probe
The Probe's red led is turning on and of depending on the proximity of the metal as it should but when I Send M119 to the machine it gives me
x_min: open
y_min: open
z_min: open
in either case whether the light is on or off
I made sure of the wiring is setup the correct way.
Any ideas ?

Thanks for your attention !
The board I use is SKR v1.4 turbo and there is a pic attached
and the probe's model LJ12A3-4-Z/BY 5v-36v
And also the way the connectors is attached is a included with the images
I forget to tell that I tried to use this probe on an Arduino board and it worked.

Don't use the Z stop for the input. It has hardware pullups that interfere with the probe.
Use the probe port. that is why it is there.
Remember to update your config
disable #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
and enable #define USE_PROBE_FOR_Z_HOMING

Hello Dust
Thanks for replying.
I tried it out and it worked.
I am wondering with this happens I tried to turn of the pull up resistor and also the pull down resistor, I tried every single case and didn't work
although other people use it with no issue.
Second thing i have alittle problem with the Z offset
When I home, the printer homes to the coordinate z=0.7 and that is the offset I assigned
and it is supposed to home to Z = 0
Can you help me out ?!
Thanks

And this is why I like reprap.org Forum always learning more.
Myself have never had a Problem using
#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
Or maybe it could be this is why I had some problems on My MPCNC will have to get some time and finishing adding end-stops.
Currently not using end-stops with my MPCNC, though may need them when I start using my MPCNC as a 3D Printer.
