-  *Using the **[revolutions / second]** value and the minimum allowed **[seconds / step]** value of the motor, calculate how many **[steps / revolution]** the stepper driver will have to make. As discussed earlier, the value selected on the stepper motor must be equal or smaller than the number of **[steps / revolution]** obtained from this step for the motor to register the signal and function properly.+  *Using the **[revolutions / second]** value and the minimum allowed **[seconds / step]** value of the motor, calculate how many **[steps / revolution]** the stepper driver will have to make.  
 +     *For example, if the minimum allowable pulse width on the motor is 8 μs/step, and the machine will produce 16 revolutions/second, then the maximum value for the **[steps / revolution]** will be around 7800.

 +  *As discussed earlier, the value selected on the stepper motor must be equal or smaller than the number of **[steps / revolution]** obtained from the previous step for the motor to register the signal and function properly.
       *For example, if the **[steps / revolution]** value has been calculated to be 7800 steps/revolution, then if the stepper driver allows for 3200, 6400, and 12800 steps/revolution, 6400 steps/revolution will be selected.       *For example, if the **[steps / revolution]** value has been calculated to be 7800 steps/revolution, then if the stepper driver allows for 3200, 6400, and 12800 steps/revolution, 6400 steps/revolution will be selected.
  
-  *Using the **[revolutions / second]** value and the updated stepper driver **[steps / revolution]** value, calculate the actual **[seconds / step]** value of the motor. This value will always be equal or higher than the minimum allowable **[seconds / step]** value of the motor.+  *Using the **[revolutions / second]** value and the updated stepper driver **[steps / revolution]** value, calculate the actual **[seconds / step]** value of the motor. This actual **[seconds / step]** value will always be equal or higher than the minimum allowable **[seconds / step]** value of the motor due to selecting a lower **[steps / revolution]** value in the previous steps.
       *For example, if the **[revolutions / second]** value was equal to 16 revolutions/second and the stepper driver **[steps / revolution]** value was equal to 6400 steps/revolution, the actual **[seconds / step]** value of the motor will be equal to 9.8 μs/step.       *For example, if the **[revolutions / second]** value was equal to 16 revolutions/second and the stepper driver **[steps / revolution]** value was equal to 6400 steps/revolution, the actual **[seconds / step]** value of the motor will be equal to 9.8 μs/step.
