I'm playing Ultimate, and after much ado I finally assembled my Industrial Blast Furnace today. The light on the front shone green, my MFE was nearby and filled up, the birds were singing and life was good. "Time to make some steel," I thought and connected the MFE to the Furnace block with a single EU-Splitter Cable (to prevent the furnace from siphoning all my EU when not in use).
It started draining power, just as expected, so I "closed" the cable. Then I put some Iron and Charcoal into the furnace, and put the power back on. Nothing happened.
Tried with Refined Iron and Charcoal. Iron and Coal Dust. Iron and Coal Coke. Nothing happened. I checked the MFE. No power was even drained from it, no matter what cable I used (tried to replace the EU-Splitter with Gold Cable, with no luck). What am I doing wrong?
