i have a steve's cart that harvests wood, saplings and apples. from the start, i turn all wood into charcoal, and the saplings and apples go elsewhere. once the charcoal is extracted from the electric furnace, 2/3 of all of it goes elsewhere. the last 1/3 of the charcoal loops back around to go back into the cargo manager. if the cargo manager is full, an insertion pipe sends it back along with the other 2/3 of charcoal. here's my problem. the cart does not use 1/3 of the total ammount so the cargo manager slowly builds up the charcoal untill it floods the entire system and i have to climb up there and empty it out so the cart can place the tree-stuff back into the manager and work properly. i had an idea that some machine tests to see if there is 3 stacks of coal in the cart. if so, turn on an engine that extracts the coal from the cargo manager untill the cart does not have 3 full stacks. the only problem is that i don't know what that machine might be. if anyone can tell me if that exists, or if there is a bettter way of doing it, please let me know i'm open to anything, so long as it does not require any more diamonds (i've started a new world and i'm trying to use as little materials as possible)
