It is very fun building automation in this, but I have hit a snag when automating the creation of specific foods. Is there a way to limit the number of an item being put into the building, and/or a filter specifically for buildings so it only accepts just what is needed for a particular recipe?
You can filter what goes in using the filter funnels and you can decide when an item goes in using the logic gates. You can for instance stop items from going into the structure by blocking their path with logic gates, and then you can have something activate the gates letting one or more of each item in. Logic gates are important for most of the automation mid to late game.
