Am i missing anything here?

[phantomcow2]

I am getting a Harbor Freight micro milling machine from UPS tommorow, i'm pretty excited about that . But the plan is to CNC convert it, i dont know a heck of a lot about the electronic part of it so im wondering if a person can help here.
I got 3 stepper motors from my birthday, i believe they are unipolar but is there some way to confirm this? I can take a picture if it helps.
When i can confirm that they are unipolar I am ordering a 4 axis Hobby CNC board.
Besides the wire needed to extend the wires coming from the motor so that it can stretch across the entire milling area, what other electronic devices do i need?
I would imagine a power supply of some sort, and Hobby CNC says i need a transformer. I read an article about a person converting a PSU designed for a computer to a power supply, is this more hassle than its worth? And as for a transformer, i have no clue what im after there.
Thanks to anybody who contributes a helpful reply

The transformer mentioned is probably for the power supply. I would go to http://www.mpja.com and find a supply. What voltage are the steppers and what's the current per phase?

I know very little about these steppers, my uncle sent them up as a birthday. He was going to make something and got a pack of 15 steppers but never got around to making it. So they are brand new, from Japan servo Co.
I have a serial # though so i iwll look up that information. Thanks for a reply

I believe the motors are 3.6v and current per phase is 2

Can you tell me what i am after on that website you gave me? I know a power supply but what voltage and any other information

If they have 6 or 8 wires, they can be used with the HobbyCNC drives. If they are 4 wires, they are bipolar and cannot. The transformer is to build a power supply. Their complete kit comes with everything BUT a transformer. Do what viper says to get the best deal on a power supply. For best performance, you'll want to build a higher voltage supply.

Thanks. I got a very good explanation frm a person. When i am at MPJA.com, what do i look under for power supplies? I am assuming single output since the power goes right to the board...
He said you want a power supply rated for 3A or more.
Would something like this work:

Was that a total of 3.4 amps for the supply, per stepper or per stepper phase, what's the voltage rating on the steppers.

Yes, that will likely work....but you can get better performance from your steppers is you stay close to 20 X the voltage rating.

[phantomcow2]

well i am having a difficult time finding the voltage rating of the steppers.
Its a japan servo co. motor #kh56km2b093.
That does not follow the same format as what is on Japan servo's website.
Is there some way to test for the voltage/amp
