Thanks for your valuable info. It really did help a lot. As i am building this CNC router for home use so my cost considerations are limited (Within $ 2000 max). I found motors and the ball screws. I am using gecko servo drive. In near future I will be building 6'X8' table made out of aluminum and tubes (I will try to keep the table as light as possible). I will have to recalculate the motors and drives probably, but I am selecting Rack and pinion for sure. Nexen group make a nice one and surprisingly the tol of the backlash is 3.2 micro meters (±0.00013 in.). Thanks again for your input and further suggestions are welcomed. There is no limit to the CNC and the power of sharing the ideas.
Cheers,
