first off check nie for the correct amount of items for each recipe some requites a full 64 stack like the redstone one, & secondly as stated above this machine requires a lot of power, I would advise having even a basic power network up before you try go to far with gregs even the starting level machines require a huge amount of power to work effectively, I would setup a geo, biofuel/mas or boiler power network before even attempting what is ment to be mid to endgame mod.
