The factories work by limiting the output, by how much there is the in provider chest next to so it doesn't continiously produce items.
Robots fly around and makes sure that every factory has what it needs and also exterminates any need for belts.

Unfortunately this design is also rather boring as it makes it way to easy to make everything in the game, so i will soon abbandon this world and move along to another 100% belt powered world, but i thought i would share this and get your thought on the design first
