Missing nuts on x-axis / gantry bolts


While going through the alignment video I noticed that the gantry was very loose when checking the vertical movement. The two large bolts (with aluminum spacers) that hold the x-axis tube to the gantry were missing washers and nuts.

I watched all the installation videos again to see if those were added at a later stage, but I think they were just missed at the factory. I had some spares in my shop, so I think I’m good now, but just wanted to give LS a heads-up.


Thanks for giving us the heads up, sounds like only the interior cap screw was holding things together. We started a few new people in gantry assembly so this will be a good learning example for them.
