| - | *Using the **[revolutions/ | + | *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. 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 function properly. |

| - | *Using the **[revolutions/ | + | *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. |
