My guess is that those motors will not be suitable - because they have high-resistance and low-current coils they will not step as fast as a motor with a low coil resistance and higher current. And on top of that you have the speed reduction due to the gearbox.
Also, the backlash in the gearbox will make it difficult to achieve precise positioning. Where gearing is needed toothed belts are a better option as they have no backlash.
You should start by measuring the torque needed to move your machine. Then select a suitable motor. The select a motor driver and power supply.
