Opinions/ideas on figuring out 8 wire steppers

Hi Everybody(sounds like micky),
I just gave this advice out to a friend on figuring out some 8wire
steppers( nema42 ) that only have wires coming out( no terminals )
Plese let me know if my logic is wrong. Thanks -Lee S.

If all else fails:
Brute-force method:
======================================================================
======
Verify with a known good motor( 4,6,or 8 wire) that the Gecko is
connected to step a motor correctly. ( ie power and step/dir signals
are good and working ) Note: always power down while changing
connections!!!!.

Now on your motor to be tested:
Test continuity for each of the coils and verify good. Put temp tape
around the coil pairs wire insulation to bundle them together but
leave room to put additional labels.

Then try all combos of single coils, 2 at a time , on the Gecko
terminals A+/A- and B+/B-, until the Gecko steps a set correctly.
As soon as you figure out the 1st stepping set, label them A1+ and A1-
, B1+ and B1- according to the Gecko terminals A+/A- and B+/B- and
remember the direction it stepped !!!!. Disconnect these now-labelled
wires and keep them isolated and off to the side. ( tape em
temporarily)

The remaining 2 sets of coil pairs should now also cause stepping
when connected to the Gecko terminals A+/A- and B+/B- . The 2nd
combinations should go in the same direction as the 1st labelled set,
if not flip the connection on A+ and A-, then the motor will step in
the same direction as the 1st set.

For the 2nd set that causes stepping in the same direction label: A2+
and A2-, B2+ and B2+ as connected to the Gecko terminals A+/A- and
B+/B-.
Now for series you can hook them up as
GeckoA+ to A1+, A1- connected to A2+, A2- to Gecko A-
GeckoB+ to B1+, B1- connected to B2+, B2- to Gecko B-
