it works either way.
M574 Z1 S2
is what the configurator creates for z probe on version 3.but as i said more important is the homing script.
Son of a gun. That's confusing.
Turns out, at least on 3.2 that M574 Z0 or M574 Z1 S2 or M574 Z2 S2 works.
It even worked with no M574 referencing Z at all.
Thanks.

Which makes complete sense since G30 only cares about M558 and G31. M574 is for endstops.

M558 P8 C"^!zprobe.in" H5 F450 T5000 R1
That would match your previous settings.
You should also check your config.g syntax by sending M98 P"config.g" This will report any errors that may get lost during startup.

Sorry guys had an internet issue. Bust testing now

I agree but when homing with z probe the documentation states that for v2 M574 Z1 S2 is needed and for v3 M574 Z0 is needed.
So something is out of sync - the firmware is right and the docs wrong or vice versa.
Curious. Thanks.

@Phaedrux
Thanks. Sorry I've been making so many changes following some of the other guys. Just getting seriously lost.
I tried your suggestion and now i at least get an error:
When homing the Z it says :1/21/2021, 6:44:30 PM Error: Z probe already triggered at start of probing move
Error: Homing failedI'm really getting a bit lost. Can you see any mistakes ?
Also the M98 P"config.g" reports this;
1/21/2021, 6:52:01 PM M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabledSo I've changed my config.g to the following:
; ##### Endstops ######

M574 Y1 S1 P"!ystop" ; configure active-high endstop for low end on Y via pin !ystop

as phaedrux says change to
M558 P8 C"^!zprobe.in" H5 F450 T5000 R1 ; set Z probe type to switch and the dive height + speedswhen you issue M119 you can see that the probe is already triggerd. the ! inverts the signal

Yes Awesome !!!! it works,
Cant thank you all enough for being helpful. Now i can sleep.

In the notes for M574 in the wiki it has this:
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 Z0 should be used.
And even that has an asterix, because you can define an endstop (for zmax for instance) and use either the probe or the endstop depending on what you call to home at the time. G1 H1 or G30.

Great Product and fantastic help.

Or am I misreading what it says?

@fcwilt Yes it does. I'll complete that sentence to include, unless you have another use for the z endstop, such as homing to Z max. Technically it could be left undefined. M574 doesn't have any bearing over the probe setup itself.
-
i find the M574 Z1 S2 setup helpful when reading other peoples config.
it tells me that they generated the config with a z probe.if left empty they could have selected none.
-
@Veti Yes, and I think that's why the config tool sets it that way for clarity more than anything else.

Rather than say it should be something specific like M574 Z0 (which does nothing) perhaps the docs should simply state what is actually true with regards to how the firmware uses M574.
Including superfluous code is not my idea of clarifying things.
Thanks.

@fcwilt It now says
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.

That seems to clear up things nicely.
