How to print multiple objects, one after the other

[makerbottracks]

Hello,I attached a jpeg of what I am trying to print. How do I tell makerbot to print the objects one after the other? That is, I want to tell makerbot, "print one object completely first, and when you are done with that object completely, only then do you start to print the next object." Previously, when I tried to print what you see in the jpeg is that makerbot made a base for all four objects, and treated the four objects as one object. As makerbot went from object one to object two, then object two to object three, etc---by the time makerbot returned to object one, the filament had already dried on the first object and the extruder clogged. How can I accomplish my goal?
