Motor driver for stepper motors

Hello, I want to control high torque stepper motor that could handle large load. What motor driver do you recommend?

2

Define "high" and "large" (numerically) please...

3

Have a look at stepper motor basics

...R

4

If possible, around 300-500N in weight. Shall I get the Big Easy Driver, Easy Driver, the official Arduino Motor Driver, or something else? Besides the driver, please recommend a controller also. Shall I use UNO, Mega 256 or R Pi2?

I suspect you did not read stepper motor basics ?

Either an Uno or Mega will be fine and probably more appropriate for machine control than an RPi.

A weight is not a torque. Torque is a twisting force, measured in N-m. I think you
need to provide a lot more information about the mechical setup otherwise we
will simply be guessing.

[ But you are being a lot more logical than many in asking before buying a motor
or driver, which is great! ]
