3 Axis CNC router

Sorry for the high-jack but I've been wondering about best gantry geometry recently. I half remember a thread comparing some different alignments with simulation of force in various directions. Do I remember right? I kind of remember this 'L' shape being best, but I'd like to re-cap.

Not sure about the Simulation thing but I can tell you from experience having built many many machines using this "L" design it works perfectly for Wood routers and is very stiff.!
If your wanting semi milling machine stiffness then you'll maybe want to go with something a little stiffer and heavier. But for wood routers and light Aluminium work then it's plenty strong enough.!
