So one motor rev = .1 travel. That seems a heavy gantry weight for a 2x3 table?
The weight on accel/decel (inertia) will probabally be your bigest limiting factor.
If you can reduce the Gantry weight it would help.
If you are routing only, you do not require quite the same rigidity as for milling.
with 4000 rpm you have a bit to play with for reduction, the inertia ratio between motor and load will be reduced by the Square of the reduction, so every little makes alot of difference.
