I am looking into building my first CNC router. I am wanting to buy the HobbyCNC EZ Driver and I wanted to use this power supply (http://www.interinar.com/fs-15024-1m.html) Would this work?

Looks like the one I am using / used. It is a great start but if you decide to up the stepper motors to near the 3amp limit the supply will start shutting down on you ( ask me how i know ).

I bought mine from these guys:

what size steppers are you using?

I am planning on using a 24v 15amp 350w power supply for the hobbycnc board like the ones you have posted a link to, what did you upgrade to when you outgrew yours?

I built mine several years ago by building with 3 separate 24 vac 5 amp transformers that were individually rectified, then smoothed with capacitors, and then the 3 + voltage outputs were tied together (parallel) and the grounds were tied together.

This gave me about 34 vdc and 15 amps. I added in a couple of 12vdc fans to the box fed by a wall wart. Works good. The box is an old desktop PC case and the big on/off switch was retained to turn on the power.

I also added a drain resistor to the + output to ground via another switch to ensure that the capacitors can be drained after the power supply is turned off. I don't want to be the discharge path.

Hope it helps.
