To All;
There has been mention of people having various bits and pieces to assemble
a stepper power supply. Some have pertained to Dan Mauch's 3 axis 5 amp card,
others have been more vague.
I think most of us would cringe at the thought of a prized chunk of
material being tossed in the scrap bin. Even if it is a hobby, expense is
expense. I would like to hear opinions on what "ideal" components would be
for a typical 3 axis 5 amp at 36 or 40 volt system such as Dan's and some
stuff aimed at the Nema 42 guys amongst us. A power supply for the people
that have 70 or 80 volt, 7 to 10 amp chopper drivers. I'm sure there would be
a difference between chopper driven systems and series resistor driven
systems. What is required? Three times rated motor current? I'm assuming for
one axis, not three. Dan mentioned a 15 amp supply would be good but was that
for a three axis setup or for one? I'd like to get the best parts so that I
can avoid heart ache later....

Is there a FAQ specifically addressing these issues? Capacitor values,
Transformer KVAs, bridge PIV's and amp ratings etc. Would one fuse, circuit
breaker or ? to protect a drive axis? Thanks in Advance all!
