rectangular grid calibration

Hi all. I have configured my smoothie board to use the rectangular grid bed calibration. In the config file I have also set to true the value to save the calibration grid
At the start of every print, the printer does the hole calibration routine, all the times.
I would like to just do the calibration routine once and may be repeat it once in a while, not before every print.
In theory, now my board is doing the calibration and saveing the calibration grid? How do I load that calibration grid and avoid the board doing the probeing routine every time?

Thanks in advance
