Duet 3 XYZ Optical End Stops configuration

Are they active high or active low?
If the M119 shows not stopped when they are in fact stopped, you need to invert the signal pin by adding a
!in front of the pin name.Example:
M574 X1 S1 P"!xstop" ; X min active high endstop switch M574 Y1 S1 P"!ystop" ; Y min active high endstop switchHave you seen this> https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches

tried that also, same result. Seems a dead end so far.

What board are you using?
What firmware are you using?
I'm not aware of any Duet 3 board with those pin names.

Duet 3 / RR3 what is the pin name for IO_0
Here are some endstop setups taken from one of my printers using a Duet 3 Mini 5 running firmware 3.3.

Can you take and post a photo of the endstop connections to the board?
With firmware 3.3 (and probably newer) you can view endstop status with the DWC Object Model selection.
And, just FYI, with a Duet 3 board you don't need to use the ^ character as the pullup resistors are always active.

@dingo007 welp a multimeters says it appears i have a bad cable, no power at the endstop, but 5.24v at the header pins
-
so to update all.... i have a new cable and end stop on the way... and yet what do i find....
the simplest of mistakes by reversing black and white wires by the builder, I chase issues for 2 days.

-
@fcwilt i have the proper omron cables being delivered tomorrow, no idea why they solder these ends.

I'm sure I would have caught on eventually. Nice catch.

@dingo007 and this is fixed now, XYZ all home correctly now,
thanks for the config hint

Glad to hear all is working.
Just FYI that M574 for Z is not needed.
From the docs:
The S2 option of M574 is intended for use only when axes other than Z are using the Z probe for homing. The only printers known that do this using Duet electronics are the RepRapPro Ormerod, Huxley Duo, and Mendel Tricolour machines. When using the Z probe to home Z, M574 Z has no bearing on the probe setup or usage. A Z probe and a Z endstop can both be configured at the same time. G30 calling the probe setup with M558, and G1 H1 Z moves calling the endstop configured with M574 Z.
