Re: Question on Power Supply

I would use a 24v 7.5a power supply. That would give you max amps
for your driver on all three axis at the same time, theoretically....

look at www.mpja.com. They used to have a 28/14VDC power supply
that works very well for the smaller stepper drives. I use mine
with a Xylotex.

I found it easier to buy one off the shelf than get a
cap/torroid/bridge + whatever else to build one. If I ever go to
Gecko's and need 60+ VDC I would build my own.
