Steppers, Series, Parallel

[Jonathan]

That's a surprise because I tried wiring in parallel once. Once being the operative word. I got little appreciable speed advantage and lots more heat.

But aren't your motors on mains voltage, or something silly high, in which case it's hardly surprising that they would overheat in parallel?

Also, why is everyone worrying about Volts, our drivers already have lots of Volts? Parallel wiring requires twice the Amps.

See the post I linked to earlier - it's because the inductance is 4 times greater when in series, so you need a higher voltage to 'overcome' that.
