Me and a friend love playing this game casually but hate dealing with storage early. So we're playing the game normally but with the one mod. In the first picture you can see, we have all items stacking in 9999 stacks. But for the sake of flow of the game still going normally, I wanted my machines to work at a somewhat vanilla way. I turned on the input buffer so that any machines with an input would now run off a default stack size. Keeps my manifolds running smoothly. All my normal machines (miner>smelter>constructor) are doing just fine. they stop inputting at 100 ore/ingots, while allowing max stack overflow as a buffer. But my coal generators and biomass burners are ignoring the input buffer, which is making the first ones eat everything, and neglect the ones further down the line by increasing amounts. which can be seen in the 2nd image. My first gen in the line is at 1600 coal, and the last gen in the line is at 0.
