Ok, this is what - the third or fourth thread you have started asking exactly the same question? That's not really the right way to do things. It makes for a lot of clutter and it fragments the replies. There is no way others can get anything useful from the information you come up with.
The answer is still the same as in the other threads, that motor pulls more current than it should to be the best alternative on an i3. There are cheaper motors that will work better for you. The details are the same as in those other threads.
What is there about the Alltronics stepper that makes it attractive to you? You keep asking about it, so there must be a reason you have latched on to it rather than any of the other thousands of motors out there.
Are you confused about amps? Motor power is not rated in amps, it's rated in torque. High current motors are *not* high power motors. You can get the same torque at a number of different current levels. You match the torque to the printer. You match the current to the driver. They are independent variables. There is no need to go to high current to get the proper torque.
