Hello. Looks really good! Is there any benefit if looking a how rigid the machine is by having the gantry rails on top and at the bottom, compared to mounting both on the same side?

For example if we compare these 5 options, which one is the best for rigidity?

  1. Both rails on the spindle motor side of the gantry, ballscrew in between rails.
  2. Both rails on one spindle motor side of the gantry, ballscrew in between on the opposite side.
  3. One rail on the spindle motor side side, ballscrew on the same side and the other rail on the top of the gantry.
  4. One rail on the top, one at the bottom and the ballscrew on the opposite side of the spindle motor side.
  5. One rail on the top, one at the bottom and the ballscrew on the same side as the spindle motor side.
