To completer the wish list.......profiled linear rails not SBR rounded type.
The table would have tapped holes not tee slots.......just my opinion.
Steel is heavy which is good for vibration damping and rigidity and can be welded much more simply, whereas aluminium is too complicated to consider anything but a bolted mode.
The Chinese CNC routers are relatively cheap because they are made by the hundreds to specific cut sizes without having to cut and try in the build.
In the end, all CNC routers follow the same design it's just the fixing that alters.
A 6040 "look alike" DIY build with improved characteristics will cost you twice as much as the original bought item and not give you more bang for the buck....and you will not get paid for your labour/time input.
