One wire, two cargos. The MC3D Cable carries both Redstone Flux and Filament Units down a single line. It connects automatically to printers, fabricators, Filament Racks, generators, and any other mod’s RF machines — no configuring faces.
Power
The cable moves standard Forge Energy, but modestly: 2,000 FE/t (tunable in config). That’s plenty to run this mod’s machines, and you can use it as a general-purpose power wire for any mod too.
It is deliberately not an endgame power backbone — for serious throughput, bring a dedicated cable.
Filament Units
FU is pulled on demand. A printer wired to one or more racks drains them the instant its docked spools run dry, so a single rack can feed a whole row of machines. Transfer is lossless — no FU lost to distance.
Crafting
Cheap to craft, and one batch yields 6 — enough to wire up a small machine row from a single craft. Pair it with a Filament Rack reservoir to keep your printers fed.
