and
M119
Endstops - X: not stopped, Y: not stopped, Z: no endstop, Z probe: not stopped

but if i trigger it, movew X to home manually, M119 says the same

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.

ok so now X homes fine, Y doesnt

@dingo007 welp a multimeters says it appears i have a bad cable, no power at the endstop, but 5.24v at the header pins

dingo007

@dingo007

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.

@dingo007

So everything is now working?

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

@fcwilt said in Duet 3 XYZ Optical End Stops configuration:

I'm not aware of any Duet 3 board with those pin names.

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.
