thanks very much

@dc42 I am wondering whether you received my first board and whether you need a AOZ1284 as I have one in my possession

Thanks!!

DWC Field?? (I struggle with acronyms)
Is that the field in the UI where you can send a G code?

Yes I am sure I will, Thank you so much for all your help. I have decided that I will do my own macro from scratch rather than take the quickie (not!) route by shoe horning someone else's code into the mix.
Thanks so much !

@JoergS5 Sorry if I sound frustrated, but I have been doing 3d printers for many years, built a few and got lots of experience with Marlin and smoothie. This is my first experience with CNC and Reprap coding and it is doing my head in. Apologies all round.

I guess I just need to mark solved and go away and weep with frustration. I know the answers are there somewhere if you know what question to ask. All I wanted to know was what E0 L0 and S1 refer to in that command. I think I can work out the others.

OK thanks got it
Could you tell me what the parameters in this command refer to:
M585 Z50 E2 L0 F500 S1

According to the wiki
Parameter must be only one of
Xnnn
Y-nnn
Znnn

Looks like I have it, I need to add the HI to any G1 command that is looking for an end stop command to make it trigger.
Like G1 H1 X50

Is that right?

Thanks, slowly getting there. Guess I need to understand the G codes and it is a steep learning curve.

Oh thanks, now we are getting somewhere. Just to be clear.
If I define an endstop. with a connection setting in config.g, then that definition will be used regardless even in a different tool?
Also I need to tell it to respond to endstops at all times, not just homing? (In G1).
If I define a specific pin for Z axis end stop, that will be also used for the probe?

I guess I am asking the wrong questions. I could use another macro with G38.2 which seems the way to go, but the original question still arises. How do I tell it to use one of the pins IO_0 through 8? Just a basic programming thing...
When I define an endstop I use M574 Z2 S1 P"!io1.in"
There you are the config.g file says use io1.in

I just don't know how to tell the board to use one of the many IO pins to do what I want. Before I activate the macro I need to tell it which connector to use. This is the original question I asked. The macro assumes that it knows which connector to use. It doesn't. How do I tell it?

Guess I am back to simple Z probe then...

That is kind of complicated for me. If I connect it up as a Z endstop then it triggers. Which I suppose I can live with. Its just that I have seen loads of Utube videos showing the probe sensing all three axes using the gizmo I have pictured. Now all I need to know is how to configure a Z offset for the depth of the device (which is a nominal 10mm but actually 9.82mm)

For example, the documentation says "The Duet 2(WiFi and Ethernet) and Duet 0.8.5 provide a dedicated 4-pin connector for connecting a Z probe"
It does not mention the Duet 3
..Or maybe I just cant find it! I don't know how to define connectors, unless I have a specific example like for end stops.

Sorry perhaps I am not making it clear. I have a DUET 3 and there are lots of I/O ports. I just need to know which one to use and how to tell the routine to use that port as a trigger.

I have defined a T1 like
M563 P1 D0 H1 F0 ; define tool 1

The probe sets off looking for something
...but still don't know how to trigger it. Where to plug in the switch and how to tell the software! Sorry if this sounds dense.

Hi The tool is placed at the point on your work that you wish to record as position 0,0,0. This is so you don't have to program an offset from the home position and maybe miss your piece of wood entirely. After you have probed, the CNC machine has a new home position and you remove the tool (crocodile clip attached to the bit) and replace it with the router. (Actually the router was there all along as it forms part of the XYZ sensor by completing the circuit and pulling the polarity of the pin down to 0v)

@JoergS5 Please can you tell me how to define tool 0?
Say I want to plug my probe into Io_1 on the board. What do I actually add to the macro to make the board understand to read the state of that port? Forgive me but I am new to this and I am not a programmer.

@chrishornby .. and this is the error I get when probing which is why I need to define the tool pin I guess:

Just the one probe as per pic attached. Works fine as a Z stop connected to Io_1
