Duet 3 XYZ Optical End Stops configuration
-
I have a duet 3 board with optical endstops on X and Y and a BLtouch on Z
rr config tool isnt much help deciphering how to configure themTheir OMRON EE SX671 Optical switches, wired Estop to IO_0 and Y Stop to IO_1
research says wires red 5v, yellow ground, black io.in being pins 1 34 ... is how their wired
RR3 config says, which I am sure I havent properly configured.

Endstops - X: no endstop, Y: no endstop, Z: no endstop, Z probe: at min stopcan someone enlighten me to how they really should be configured ?
-
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

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.

Endstops - X: not stopped, Y: not stopped, Z: no endstop, Z probe: not stoppedbut 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.

@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.
