Middle Assembly should it glide effortlessly?

So I have most of it built. I tried to go through the squaring process and I think I’m mostly square. But should the middle assembly glide effortlessly on the rails? Right now, I have to use two fingers and can move it, but it isn’t effortless. I know it’s hard to quantify but thought I’d ask

No, there should be some resistance.

Whew! Thanks for that. Moving on to next step then! :slight_smile:
