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

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

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)
