Hello,
I saw that a thread has been made about how the buildcraft pipes don't extract the correct items from canning machines.
The same thing happens with Induction Furnaces. I put an input pipe on the top which places the ore/dust in the top slot to be smelted (Doesn't use both slot though :\). Then when I go to extract, I place a wooden pipe on the side and it extracts the ingots first then begins to extract the ore/dust that hasn't finished smelting.
Not sure if this is a IC bug/problem or a buildcraft one.
All the old machines work, just the Induction Furnace & canning machine.
Not sure what you can do about the items to only going into one slot.. I mainly want the increased speed to be able to smelt glass in large amounts 
Cheers
