I'm thinking because I used an import bus instead of a hatch it may have borked it... I figured bigger is better. It works fine for silicon/aluminum but I'll craft up an lnput "hatch" and see if that fixes it. Thanks for the help.
For the EBF I use both the input hatch and inbut bus. You can go only with the hatch, it can accept both items and fluids, but it acts weird if you are sending iron from a chest. From my experience, if you are pumping iron from a chest, the first ingot will start the process, but the rest of it will go from the upper slot to the bottom slot, and it will not go into the machine, from there.
It is much cheaper anyway to have as many either input or output buses, as possible, I do this with all the GT multiblock machines (the tool tip tells you the minimum amount of casings needed, the rest can be anything (except the obligatory parts, of course)).
Oh, with the EBF, if you use 4 energy hatches, you can actually run out of slots, so make sure you also use middle bottom block, for either the output or one of the inputs.
