Grazing incidence 800 eV Ar+ sputtering on a Cu(001) surface leads to the formation of nanogrooves in which only 3 layers are involved. With high resolution LEED we found that initially the distance between the nanogrooves L depends linearly on the sputter time: L=L0+St. Both the initial average distance L0 and a separation rate S depends on temperature. For sputtering along the  and  azimuths, a similar L0 is found while a higher slope is observed along . For increased sputter time, L clearly saturates for sputtering along the . Annealing experiments of initially created grooves show a similar separation rate S, indicating that this behaviour does not originate from the ion sputtering. The temporal evolution and observed saturation of the distance between the nanogrooves along both the  and  azimuth will be discussed.
