Cobblestone Framework - HenryLoenwind/EnderIOAddons GitHub Wiki
The Cobblestone Framework is a Machine Framework containing a Cobblestone Controller. It will generate Cobblestone by using its internal Lava and Water store. It has 3 upgrade slots that allow it to process the generated Cobblestone further.
The upgrade slots take Ender IO machines. You can put in either an Alloy Smelter, a SAG Mill or a Crafter. Esach upgrade will work on the output of the previous upgrade.
If you have Compressed Cobblestone from some other mod, put in 3 Crafters for some nice triple-compressed Cobblestone---with very low server load.
