Take a look at my second build at signature for a strong gantry design. May be that will give you some ideas. I go as far to say that its the strongest for the weight i have seen.
Now if that's your first build, i would be very careful, you will either way overbuild it or way under-build it. Both could cost you money and disappointment.
There would be difficulty driving gantry at 4m with ball screw. While the rotating nut is the solution, i dont know from where you will obtain 4m ball screw. I have to speak with Fred from BST but when i was buying from China, the longest 2510 was 3m .
In fact for such a machine i would pay sb to design the gantry for me if i were you. I or some other people at the forum could do that service for you. Just post it at the relevant work quote section. IMO that would be your best bet and save you big money on the build itself and time also, especially if you value it high.
Dont get me wrong, the things you will have to learn to design properly such a big machine are way too much for an inexperienced person. Not to speak of that even welding CNC structures is time costly and needs patience and skill, that the usual welder at a machine shop does not posses.
If you insist going the DIY way, then make a drawing, show it here and we will help you better it with ideas and critics. But speaking without drawing is a waste of time.
