Series takes same current, but cuts torque at each motor in half.

Parallel draws double current (quite often beyond capacity of a single driver).

Best way on Duet is almost always to use one driver per motor, and configure to make them work together.

No, series gives you the same torque at low speeds - unless the motors have unusually high resistance - but the maximum speed you can run the motors at before the torque starts to drop is halved. There is a calculator at reprapfirmware.org to work this out.

Aha! Thank you... I almost didn't post that, something didn't quite feel right.

Excellent clarification.
