    Love the build. Especially the care in making it accurate. Need to pick up some of those skills myself.

    In the photo it looks like the gauge is indicating off the rail support. Wouldn't you want to align off the rail? I have used round rails and the supports are beat up and don't reflect the condition of the rail itself.

    Yes, you are probably right, off the rail would be best. My extrusion supports were clean so I thought why not. I should check against the rail though.

    Pretty similar to what I'm working on to rebuild my machine. One thing I don't understand: how does the gantry attaches to the ballscrew?

    It's a little crude but very stiff.

    I don't have access to a lot of metal working tools so I relied on basic extruded shapes cut at the supplier. The gantry sits on 3x3" angle bolted to the bearing blocks. The ball screw connects with 5x3" angle bolted to the bottom of the 3x3
