Big Epoxy Granite machine, Which frame is better ?

[EZELab]

Edit: I would be tempted to go for No2 image

Thank you for your replay.
Yes, design #2 have many Advantages, Easier to align, Easier to machine flat, uses 3 motor not 4.
But will it add any more stiffness more than the #1 design ?

I believe it will, a fixed gantry has got to be more stable than a moving mass gantry, the only thing is you need more room for the moving table.
I have a fixed gantry and no problem at all.
