Masterful Machinery Upgraded

[1.21.1-0.4.0] - 2026-09-02

Added

• Mekanism heat ports. mm:mekanism/heat stores heat and lets recipes spend it, the same way the energy port handles FE. Thermodynamic Conductors, Resistive Heaters and Fuelwood Heaters feed an input port; an output port pushes its heat back out into anything Mekanism will take it. Recipes use "amount", and ranges and rollGroup work on it like everywhere else.
• Port config takes capacity for how much heat it holds, plus optional heatCapacity for how much the temperature moves per unit stored, and inverseConduction for how fast heat crosses the boundary. Both have sensible defaults.
• Available from KubeJS as .capacity(...), .heatCapacity(...) and .inverseConduction(...).

Fixed

• Recipes no longer drain a port every tick. An energy or heat input written as a plain mm:input/consume was consumed once per tick instead of once per craft, so a recipe asking for 2000 could quietly take many times that. Inputs marked per_tick: true were always handled correctly and are unchanged.
• Jammed machines stop consuming. A machine sitting at 100% because its output is full no longer eats energy or heat while it waits for room, and no longer produces per-tick outputs.
