I hang my sled from my top beam when the machine isn’t in use. I drilled a clearance hole for a piece of 1/4"-20 threaded rod and hang it on a similar hole in the sled.
It probably doesn’t matter, but it makes it very easy to load and unload the machine with the sled out of the way. Also means that the sled isn’t protruding out in front of the machine, so I’m not tripping over it while I’m trying to walk by.
