I took turns off the transformer so I had about 78 volts DC with the rectifier and capacitor hooked up. Here is a link to that. http://www.cnczone.com/forums/genera..._windings.html
I used the PMDX 126 BOB because it has a built in power supply that can be powered with 110 or 220 volts ac. After using the PMDX 126 I found many more great things about the board. I will help any way I can.

I decided to use a Smoothstepper and a C23. Not the cheapest solution, but I run some pretty long jobs on my smaller machines, and I would like to take as much load as possible off the CPU. My smaller machines both run PCI LPT ports to G540s. This is my first servo based machine.

I picked the C23 because it provides a charge pump, selectable input (pull up or pull down) operation, 0-10VDC analog spindle control, and a few other features along with giving me screw terminals for everything. The C23 gets its power off the Smoothstepper.

The Smoothstepper can either be USB or externally powered. I'll probably go with external power. I just don't trust the USB power on most machines. Heck I have one on my desk with 6 ports. 4 will power devices and 2 won't, but otherwise they work fine for things like camera links.
