Some advice for my Endstops

Tim-C.

Hi, once again I am running into a Problem while setting up my first Duet 2 Wifi board. I cant get the inductic endstops from the Sidewinder X1 to work. The Consol output is:

M119 Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped
and
M574
Endstop configuration:
X: low end switch connected to pin !xstop
Y: low end switch connected to pin !ystop
Z: low end Z probe

The status does not change when they should be triggerd or not.

config.h is:
; Endstops
M574 X1 S1 P"!xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"!ystop" ; configure active-high endstop for low end on Y via pin ystop
M574 Z1 S2 ; configure Z-probe endstop for low end on Z

; Z-Probe
M950 S0 C"exp.heater3" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X33 Y-47 Z2.5 ; set Z probe trigger value, offset and trigger height
M557 X15:285 Y15:285 S67.5 ; define mesh grid

The +5V for all the Endstops and BLTouch is comming from P1 on the Expansion.

What am I missing? Is there a nother way to messure the functionality?

Best Regards Tim

Can you describe more what you mean by this?

Do you have any electrical specifications for your inductive sensors?

They are often not compatible with the Duet 2 endstop connections.

Can you also please post a picture of one of the endstop connections to show the wiring from the inductive sensor.

@tim-c Without knowing for sure since I do not not own such a printer, a little bit of googling suggests that these are 12-24V NPN inductive sensors which means that they require at least 12V to work reliably.

Have a look in this old thread: https://forum.duet3d.com/topic/12056/npn-12v-endstops-at-duet-wifi

If this is correct, it will behave as my old PL-08N2 inductive probe and output near input voltage when near a metal object. Just make sure that your input port can handle the higher (>3.3V signal) voltage.
