Feedback on 1.0 design

You are nearly there but you are misunderstanding the fixed gantry advantage. The supported rail mounts to the table and the bearing blocks go close under the tool tip. Turn the rails over and get the support where the cutting happens, where you need it, lose the overhang.

nice design njcook.
like others said profile rails the way to go.
and if you haven't already,make provisions for splash guards/coolant return during the build keeping the screw and rail free of it.
