This is why I made my machine level instead of tilted backwards. Tilted back, the lead goes up, then has to bend down (usually) to the floor. It's not nearly as much of a bend to go from straight out of the machine to the floor. The tilted back designs are usually on little low, stubby carts where it probably would be a pain to view the controls. If you make it at a more convenient height, you won't have to make your lead go through such contortions!
To each his own-----maybe it doesn't make much difference, but for me, in normal use, it's less of a stress or kink on the lead when it's sitting level. It looks better and I can read the dial fine that way, and the wire has an easier time getting pushed through less of a bend too, so that's what I did!
Carts are a personal thing---that's the beauty of making your own. You can use your own ideas and reasons for doing things.
