if you have stall detection enabled, you may get stall warnings, that's normal. I tend to get them during prints on Z when I do fast Z hops because the sudden stop during those moves also generates back emf.

@oliof
thanks, that's interesting to know, ive mainly seen them on Z axis , but have also seen them on X too now and again.i suppose i could set a new sensitivity (S parameter) at the end of the homing routines .

Ok i have noticed this:-
hit the "emergency stop " button and all i run is "max z home. g" Macro as above , but its always motor 0.4 that doesn't move.
if i switch on the printer (mains on) in the config i run the same macro "max z home. g" and its motor 0.4 that doesn't move .this seems to happen 100% of the time well i did 20 tests and it happened each time.
so here is where its gets a bit odd, i swapped stepper motor wiring 4 and 6 , re did config so the stepper motor order in M584 was in the correct order again , but now its stepper motor 0.6 playing up.
so could this be a software issue as it always seems to be the first stepper in the M584 list , or just coincidence?<

No more Gurus out there playing with the Duet 3 mini5 tmc2209
I setup homing via stalling and it worked. Compared to an actual endstop sensor it made quite a thump.
I quickly installed actual endstop sensors.
I don't like thumps.

@moth4017 since you swapped the wiring as well it's hard to say.

I have the x y sensorless homing well just a gentle tap for homing,
the Z homing max also works with a gental tap, but sometimes the motor just stalls and doesnt move.<

@oliof
i suppose it rules out if it was a mechanical issue .. -
sure, but I would check the wiring on both ends anyways to ensure there are no bad crimps.
-
thats has caught me out in the past before , that would be a nice easy fix :), but not this time .

Ive tried settings from low to high in the sensitivity H settings from 50 to 700 current from 10% to 100% .
it does seem to be 90% of the time the first stepper motor listed in M584 stalls

Well, that rules out that theory.
I don't use the "stall guard" feature and know only the basics.
Good luck.
