i only press it on a chest. I have 4 chest hooked to my quarry. I sort them when cleaning them. I am new trying to figure out a sorting system. I got 1 diamond transfer in taking cobble, dirt, gravel to a void pipe. 1 is taking coal to my Coke furnaces. 2 is taking all ore to one chest, and the other one is taking the rest of the stuff to those 4 chest, so to help clean them out I like sorting them into rows. It just takes me 1-2 min to sort 1 chest thou.
I read somewhere to use a relay. I made one and not sure what to do with it.
