This seems like a good solution, thanks. After posting this I also realized I could just pump the ores directly into the pulverizer(s) from the drill and filter off any I didn't want automatically processed into an ME interface. I'll try both out and see which suits me best.
Another general question for the thread. I'm trying out Ender IO for the first time. I know you can have multiple conduits in the same block but do I need to make separate connections for each type of conduit? For example, I have an igneous extruder setup to keep a barrel full of obsidian. Obviously, this machine needs a constant supply of both water and lava and I also need it to be able to recieve a redstone signal from an ME level emitter once the barrel is full. So could I have the lava, water, and redstone signal all coming into one side, or would I need to have each input conduit on a different side?
