Duet 3 Stepper coils pairing

[LordOfDav11]

I'm not sure in the documentation. What pins are the corrent pairs of coils for stepper motor?

A2+A1 (one coil) and B2+B1 (second coil)

or

A1+B1 and A2+B2?

Do I have my image drawn correctly?

Thanks for answer.

Yes, that's correct. So your diagram is correct too.

I have a running D3, with expander boards. All above is correct.

The notation using AB and 12 is confusing indeed. Had the same problem in the past.

A more intuitive notation would be for example A+,A-, B+,B-.

Yes, that's even better.
