Array Question

The best way to array an object with a 0.6m (for example) gap? I have tried it with Instance (Directional Array) but it didnt worked as I want. So I duplicated each cube, snapped it, moved on 0.6m and so on. Is there a more smarter/less frictional way to do that?

Best way that I know of is shown in the linked image. works with Instance directional array or advanced. The image below shows the advanced option. I also use advanced for radial arrays.
