M558 P8 C"^!zprobe.in" H5 F450 T5000 R1

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

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.

Where does it say that?

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.

Good job and thanks.
