Basically i have a store room with a chest for each item from my quarrys and have just started a factory type area, my plan was to have redstone/pneumatic tubes coming out of each of the chests joining into one tube that then goes along the length of my factory area and has retrievers attached to it at intervals with Retrievulators next to it with a Automatic Crafting table. So the crafting table would pull the items from the chest BUT if its set to pull say, 9 Diamonds to make a block it will be 9xInf until the chest is empty. What i want to know is, is there anyway to have it sense the item has been pulled out as soon as its pulled so i dont have the entire stock emptied? And if not is there a way to have the items that arent wanted sent back to their original chest as atm they go back to the first chest they meet.
