Newbie- Power Supply

[mxcapo]

Hello all,

Sometime ago I decided to build a CNC machine and after some investigations I thought that I should start by building the power supply.
I then searched in the web and found this PS (0-30 VDC STABILIZED POWER SUPPLY WITH CURRENT CONTROL 0.002-3 A)
http://www.electronics-lab.com/proje...003/index.html

At that time I bougth all the parts and all my problems started because that PS has gone through many modifications, versions, etc and that thread has become huge (200+ posts). I've spent so much time and $$ on that PS that I got demotivated.

My question for you is because I read somewhere that the most suitable PS for a CNC project is a basic unregulated linear Power Supply.
Should I continue building that power supply or is there any other option easier for my final goal (CNC machine)?

The steppers I got are SanyoDenki 5.1V 1A.

I'd appreciate your help.

If the transformer has a suitable output and VA rating, then you may be able to salvage it some and simply add a bridge and capacitors and you have a very rugged linear supply.
Build it the right size and you do not usually need regulated for Servo/stepper operation.

All you need is a simple supply, transformer, rectifier, filter capacitors...along these lines:http://pminmo.com/simple-power-supply

Thanks for the help.
The transformer is 24V 3A.

That will give you ~33vdc after the bridge.
