Thanks for your help, have now applied full resettable fuse and 10K resistor fix. Funny though as could not find original fault.
Whilst fixing I have also recognised a further issue but as is unrelated I have created a new thread.

@dc42 thanks for your reply
I can confirm the x and y do move after I over wrote the home all m564 s0 h0 but the z axis dont move And makes shuddering noise
If it's a Cartesian or CoreXY printer with a leadscrew-driven Z axis, that may simply mean that you have set the Z maximum acceleration to high in your M201 command, or the maximum speed too high in M201.
A bad crimp connection in one of the cables is another possibility. A faulty Z driver chip on the Duet is also a possibility. You may wish to test the two motor/cable assemblies individually using one of the other motor outputs connectors on the Duet.
@dwfl89 said in Question about using existing and some new parts with duet 2:
Completely missed that there was a post saying 6 pin ph in it.
You did post pictures of the other end saying you wanted to make extensions for that side; otherwise I think I would have made a bigger point of it.
The female PH connectors and terminals are readily available at the usual suspects. You may need other dies or a new crimping tool depending on which you used for the XH. This is the reason I prefer the manual tool like Engineer PA-09, crimps anything with a little practice.

@stevo said in Impulse buy why do I do it !:
I think I may have made a mistake with an impulse buy on 2 motors to run a Z axis on a Corexy printer I have just started building.
I read the the information on buying Nema 23's in the selecting motors section on the site.
I have purchased 2 Nema 23 Bipolar 0.9deg 1.26Nm (178.4oz.in) 2.8A 2.5V 57x57x56mm 4 Wires.
I have taken the 2.8A literal as a max just looking for a yay or nay please.
They sound similar to the 1.8deg Nema 23 motors that I use for testing the Duet WiFi/Ethernet at max current. They will be fine at between 2.0 and 2.4A current. Use 24V power, or keep the speed low.
Many thanks for the reply very much appreciated.
I'm running version 3. A previous unit I built had no issues, but I'm guessing I got lucky with a BL touch that would work at a lower voltage.
I'll have to add some terminal blocks and run it off the BL touch. Might not be a bad idea to update the BL touch section of the wiki, to warn about expansion IO not supplying 5V if connected to external power supply.
Can you confirm that you are still running main firmware 2.02, as shown in the M122 listing in your first post?
I can ask chrishamm to look into this message, but he will probably ask you to upgrade to Duet Web Control 2.0.0-RC6, available at https://github.com/chrishamm/DuetWebControl/releases.
There are lots of equivalent parts for that connector. Here's one: https://uk.farnell.com/multicomp/mc-254-50-00-st-dip/connector-header-50pos-2row-2/dp/2843537. And here's an example of the mating ribbon cable connector: https://uk.farnell.com/3m/d89150-0131hk/connector-rcpt-50pos-2row-2-54mm/dp/2672519.
I guess assumptions is the mother ... I just spent today playing with two z motors, and two limit switches to sync up Z axis, and assumed adding a 3rd would require a end stop.
Half the "problem" "solved"; still interested in hearing where on the to-do list general I/O triggers are though.
(Edit: Come to think of it, probably something that gets solved with v3 anyways (beta1 has no M581 support). Wait and see:)
