HephaFix is a tiny compatibility addon that lets you fully automate the Hephaestus Forge from Forbidden & Arcanus using Pipez (and any other mod that talks to item capabilities).

By default, the Hephaestus Forge can’t be piped into or out of its center item slot, which makes full automation awkward. HephaFix fixes that by exposing the forge’s central slot as a standard NeoForge item handler, so Pipez can see and use it like any other inventory.

Features

✅ Adds proper item capability support to the center slot of the Hephaestus Forge

✅ Works with Pipez item pipes for both insertion and extraction

✅ Also compatible with vanilla hoppers and most other item-transport mods

✅ No configs, no recipes, just drop it in and your forge becomes pipe-friendly

How it works

HephaFix doesn’t edit Forbidden & Arcanus itself. Instead, it:

Locates the forge’s internal inventory handler, and
Bridges the main forge slot to NeoForge’s item capability system,

so Pipez and other mods can push and pull items directly from that slot.

Requirements

Minecraft: 1.21.1
Loader: NeoForge (same version you use for your modpack)
Mods: [Forbidden & Arcanus] – Hephaestus Forge/[Pipez] – for item transport (optional but recommended)

Notes

This is a third-party addon and is not affiliated with the authors of Forbidden & Arcanus or Pipez.
If a future Forbidden & Arcanus update changes the Hephaestus Forge internals, HephaFix may need an update as well.
