Hello,

when producing Refined Iron in IC2 (experimental), you need one Iron Ingot/Iron Dust and 6 Compressed Air Cells and get as an output one Refined Iron, one Slag and 6 Empty Cells.
You produce a Compressed Air Cell in a Compressor, using an Empty Cell.

My request is, for the crafting system, to identify that loop, and only uses an as low as possible amount of Compressed Air Cells (eg. 12 for two cyles, or 10% of the needed amount, but not all 600)

At that point of time of the pre-calculation you can not assure that for all possible crafting operations the pre-required matieral is available if we would allow results of prior craftings into the next cycle.

But you can do this by crafting a single one and in multiple steps until a threshold is reached.
