You said that you watched a few of Marty's videos. That's a good start. Watch a lot of them. He's an excellent teacher. I watched many of his videos several times before attempting anything on my own. Gary Campbell and Franco also have great videos. Don't forget about the videos that Keith posts (CNCKeith).
I advise everyone to take their time with bench testing when starting out. I fiddle with the bench test model until I'm sure that I've checked everything, voltage, current, noise, heat and general operation of all components. It's a lot easier to move things around on the bench and to substitute components before you drill and tap holes in the enclosure.
Attached is a photo of my current test setup with some small ClearPath servos. The bench just a piece of 2' X 2' particle board mounted on an 80/20 frame. The whole thing sits on top of a card table. One thing that I've learned is that if I plan to use cable duct inside the enclosure, to use cable duct on the test bench. That way, if there's electrical noise caused by running wires through the same duct, it will show up on the test bench.
