Re: stepper controller boards

Hi San,

Are these John K's board? I noticed he no longer has these pix on his
site. I'd be cautious trying to "parallel" two PC power supplies.
Without some sort of series resistor, they might not want to share
current! I suppose one could use two supplies, NOT connected together,
and put two steppers on each (or even one).
