Maybe not the only approach....

Raising the gantry up and down wouldnt help much, because you still have to balance travel with clearance under the gantry.
I believe my approach (see System2) meets the requirement. In fact, because the Z axis is located between dual Y axes, there is no difference in the amount of flex. The router mass/weight is the same if at 2 inches or 12 inches of plunge! Being centered between the 2 Y reduces the possibility of flex due to the router being mounted on just one side of the Y axis.

Experience is the BEST Teacher. Is that why it usually arrives in a shower of sparks, flash of light, loud bang, a cloud of smoke, AND -- a BILL to pay? You usually get it -- just after you need it.
