Hi
I'm building a Cnc router ,
Can any one help or advise me on building toroidal power supply for my stepper motors,

I watched joe Harris build log,power supply build video, :thumsup:

How to choose components,
What size bridge rectifier ?
What size capacitors and how many, I see Joe used 4 .
What size transformer ?

Where to buy components?
Any links to wiring ?
