What does everyone use for their power supplies? Maybe a PC power supply or something else?

I had to reduce the size of my machine I am building due to funds. Instead of a 5 foot by 5 foot butting area it will have a 3 foot by 3 foot. Will have to upgrade later.

I also ordered some 8020 aluminum for the Y axis. Need to figure out how I will do the bearings for it though. I do not want to use the plastic bearings they have for 8020. Doesn't seem like it will do as well.

Your power supply will depend on the controller and motors you use. If you do a search, there are several links here to power supply circuits. The simplest is a transformer, bridge rectifier, and capacitor. Here's a picture of my controller with the HobbyCNC card. It has a 24V 10A supply. The transformer is from MPJA, everything else except for the lighted on/off switch, came with the HobbyCNC kit.
