thought i knew but i don't,help

No...that's a short circuit

A+ = Red + Blue/White
A- = Red/White + Blue

B+ = Green + Black/White
B- = Green/White + Black

Bipolar series gets better torque at very low speed, so it's not much use for you.

Also do i ignore the ENA pins on the drivers

Yes, they're active low so just leave them.

I always wire in series. There isn't lot of difference in performance, you save money on the PSU and the motors run cooler.

That's in parallel, by all means try series and let us know the difference.

Yours are on the 240V drivers though, and at that voltage (340v ish when rectified) the current can change very fast even in series, so they're better off in series to reduce the heat.

Put your motors in parallel then see if you can get 25mm/s :naughty:
(No DON'T do that, just kidding)

I think i understand it now, so should the B+ and B- colours be switched?

[Robin Hewitt]

If you reverse A+ A- or B+ B- you reverse the motor.

[deannos]

If you reverse A+ A- or B+ B- you reverse the motor.

If i follow the colours on this data sheet, the A+ A- match up, but the B+ B- seem reversed to the colours Jon posted. Am i reading it wrong, i'm looking at the diagram bottom right

What I posted is fine - as Robin said if you swap A+ and A-, OR B+ and B- the motor will just spin the other way... i.e. if you change the current direction in either phase.
