Building 8 x 20 ft CNC machine

Hi, am planning to build a 8 x 20 ft CNC machine using  servo motor. using 1 KW AC servo motor and 750W with the rated speed is 3000/ 6000 .1KW for X & Y and 750 for Z. I want to know if the AC servo motor can handle it and what type of mesa board to use and how to set the encoder to mesa board. 

Yes, and the type of Mesa board to use again can the AC servo motor 1kw rated speed of 3000/5000 handle that 8 X 20 feet CNC table.

The driver has an encoder output. And what will the ratio of the motor reduction be is planetary gear reducer ok?

Its not about size, its about weight. You typically have some base ”variables” that somewhat define your setup:
- Mass to be moved
- Max speed to be achieved
- Max acc to be used

Then you roughly find your motor/gearbox/pinion combination. You would want to make sure the torque is enough to get your acc, rpm is enough to get to the speed you want and that the inertia ratio doesnt get too big.

Then just check your gearboxes can handle the speed and torque, then see what the total backlash is and is it inside your specs.

This is a pretty crude/simple approach but should get the sizing to ball park and keep cost/performance in a good level.
