Really nps, thats what the forum is for, discussing topics and sharing points of view etc, and we are all glad to do it - thats why we are posting. Cheers.
Dual motors on Z are usually wired in series because its usually a screw involved and it does not have to move fast either. I imagine for Y it would be about some moving gantry type of machine, and that is a bit different. First off the X and Y accelerations and speeds, should be balanced among each other, as only the slowest one matters because X and Y work together and the slower one will be the real limiting factor in combined movements. And in a moving gantry the gantry will be the heaviest axis, hence it really requires more motor power than the other. Comparing to the other axis motor, a connection in series would make it certainly slower even at same load, not to mention the heavier gantry. I think perhaps this is why the moving gantry cinematic (used in many other areas), is not that well common among reprap printers which need high speeds. One axis is much heavier than the other, and moving mass is maximized instead of being minimal.
I imagine that on Y its about some moving gantry cinematic with 2 motors on Y, so you will need motors with extremely low resistance&inductance, sort of speaking in such a way that both coils combined would be like a normal motor spec (which for reprap these values are low already). Perhaps some coil resistance of 0.9 ohms or around that, maybe max 1.5ohms, so together coils would form something like 2-3 ohms ideally combined, maybe 4ohms worst case. This is just to throw some numbers. And/or also you could try use a 24v psu instead of 12v, this would really help making things snappier. Good luck.
