10MAKING A STONE BRICK FACTORY

You should now have a turtle that mines cobblestone from an infinite cobblestone generator and drops the cobblestone into furnaces to smelt stone. You’ve automated the smelting process, but you still have to manually take the stone from the furnaces to use it. That’s useful, but it’s not exactly what we would call a stone brick factory. Now you need to program a second turtle to pull out the smelted stone and craft stone bricks. Once you have your turtle team running, like in Figure 10-1, you’ll have all the stone bricks you need to build with.

Figure 10-1: The complete setup for an automated stone brick factory ...
