Furnace generator seems very hard to automately fuel (Stoneopolis 4.2)

[Harogna]

I've been at this for a few days now.
I want to semi-automate the input of charcoal into my infinity furnace generator.
My progression in the pack is: I just completed the massive storage chapter in Stoneopolis 4.2.
Tried a dropper tower from below into the central block, hoppers from the side into the walls and furnaces, the router nodes from blood magic into the central block, tried using the top of the central block but I can't because that seems the only power output and I'm still in the stage of the Immersive Engineering wires.
I can't seem to find cables/pipes that are unlocked yet that I can use. My applied energistics setup is still very small, so can't use that yet.
I can't find tips in the guide but didn't see them and tried googling it with no results.
Seeing you said it's WIP, that's why I posted this here.
This might need more information in the guide (and/or more options ingame if there is need for that, unsure if the problem is with me or the generator), because I'm kind of at a loss besides manually putting the charcoal in. If you have any tips at this stage, I'd appreciate it, I see the potential of the mod, and I like the fact you can change the look to suit your personal taste.
