Z-Probe Capacitive NPN recognized but not stopping Z-homing

Kruemel68

Hello !

I need some help
I connected the Capacitive NPN Probe to E0 Endstop and it is recognized with M119 also E0 enstop LED lights up
In the duet web control the Z probe is shown with value 1000 when sensor is triggered.:

M119
Endstops - X: not stopped, Y: not stopped, Z: at min stop, Z probe: at min stop

But when homing Z the movement is not stopping when the min stop is triggered.

My config.g is like this:

; Configuration file for RepRap Mendel 3
; RepRapPro Ltd
;
; Copy this file to config.g if you have a Mendel 3
; If you are updating a config.g that you already have you
; may wish to go through it and this file checking what you
; want to keep from your old file.

homez.g is:

Any idea ?

What do you have in your homeall.g and homez.g files? If you send a G30 command, does the head stop when the sensor is triggered?

Hello,

yes
with G30 it stops

homez is above in the thread added.
homeall is :

G91
G1 Z5 F200
G90
G1 Y-240 X-300 F2000 S1
G91
G1 X3 Y3 F2000
G1 X-10 Y-10 F200 S1
G90
G1 X60 Y0 F6000
G30
G1 Z5

as soon i am moving the head to another position the z probe is no longer stopping the head…...

using G30 in the console it works

when used in script it isn't
