CNC POWER SUPPLY

After reading through the manual for the CNC controller board I picked up on eBay, I discovered that I needed a 24v/2-6amp power supply. And then I discovered that such a power supply isn't exactly cheap unless you want to build one yourself.

From the start, I really wanted this to be a DIY project. I wanted to feel like I put this thing together myself and only ended up spending 1/5th the cost of an actual production CNC machine. However, trying to navigate through the the time/money continuum has been really tricky. I'm eating up tons of project time working on other projects that make money instead of cost money, so... I feel justified taking money from one project and dumping it into the other. It just feels more efficient. That said, I picked up a power supply on eBay for $58 after shipping. I could have gone cheaper and gotten an unassembled power supply, but the idea of being the grounding point for 24 volts and 5 amps (ie., DEATH) doesn't really sound appealing. So... I decided to go the safe route by purchasing a completed unit.

I have found over time that most CNC related items can be found cheaper in a kit or put together.

I believe you are correct. That is, as long as you want a CNC that can handle more than balsa wood or PCB engraving.

Nice find on the power supply. After cobbling together a decent box for a pair of 6x9's, I'm building an audio system for the garage. Rather than buying a receiver (which isn't immune to dust, dirt, etc out in the garage, I picked up an old car audio amp. They're sealed from the elements really well. To power it I needed 12v dc. Rather than building a kit I picked up a 250watt computer power supply on ebay for $20 bucks. I'm adding a miniplug/rca converter so my sources can be the boombox or any mp3 player.

Clever with the car audio amp. I wouldn't have thought of that.
