The z-guides that came with my kit are a u-shape, as opposed to the guides on the wiki which seem to just have a hole in them, and I'm not sure how to orient them. At first I put them all opening outward, but it didn't stay up at all. I flipped them around (opening inward), and it got the same result. It won't stand up on it's own, as the wiki says it should, and I even put the the top on just to hold it in place, but the z-stage still won't stay up at all.
I looked around on line, and Will mentions that the z-guides are different on his, but I can't really tell from the picture which way they are pointing. I'd really appreciate if someone could tell me which way they go.
