Likes AAI Industry's new machines, dislikes its recipe rewrites?

E-Tech restores vanilla recipes while keeping everything AAI adds — and has grown into a box of quality-of-life features, several of them revivals of good mods that stopped being updated.

Defaults changed in 0.21.0

Nearly everything is now on by default. A toggle you never found is a feature you never got, and turning one off is a single switch.

This changes nothing for existing saves or servers. Factorio only applies a default the first time it sees a setting, so an existing game keeps exactly what it had.

Leaving it all on is safe by construction:

• Every revived mod disables itself if you still have the original.
• Anything needing Space Age, Factorissimo or Jetpack does nothing without it.
• No new recipe changes. Four features stay off, listed near the bottom.

Recipe restore

The core feature. Always on, no setting.

• 45+ vanilla recipes restored — belts, inserters, drills, furnaces, assemblers, steam power, engine units, concrete, oil processing, labs, science packs, poles, roboport, radar, turrets, armor, vehicles, and more.
• Science packs are hand-craftable again. AAI makes them assembler-only.
• All AAI content stays — burner machines, industrial furnace, area mining drill, fuel processor, wall/gate tiers, motors, glass, sand. Their own recipes are untouched.
• Tech tree untouched. Progression stays AAI's; only ingredients go vanilla.

Krastorio 2 aware

With K2 (or K2 Spaced Out), recipes restore to K2's values, not raw vanilla — the exact state a K2 game had before AAI was added.

AAI's redundant duplicates (single-cylinder engine, wooden electronic circuit) are hidden from the crafting menu.

It never fights another overhaul

Every restore is fingerprint-guarded: a recipe is only touched if it still matches AAI's version, or contains an AAI-only item. If another mod already rewrote it, E-Tech leaves it alone.

Every decision is logged — search factorio-current.log for [E-Tech].

Factorissimo 3 add-ons

Three features, all on by default. Each needs Factorissimo 3 and does nothing without it.

Robots can finally charge inside factories

Factorissimo runs the interior roboport on a void energy source. Robot charging is paid out of a roboport's stored energy — and a void source stores none.

So that roboport can never charge a robot. Not slowly; never. Adding pads or power changes nothing, because charging never starts.

Upstream never hit this: their own hidden construction robots are defined with no energy drain.

E-Tech gives it a real electric source, plus:

• Whole-floor logistics coverage, instead of the stock radius of 2.
• Slots for logistic robots and repair packs.
• A proper charging pad count and rate.
• Every value is a startup setting.

Charging then costs grid power like any roboport — roughly 1-2 MW per busy factory. Krastorio 2's logistic-mode and construction-mode roboport variants are patched too; without that, switching a factory roboport's mode would silently revert the fix.

Factory building Mk4

A fourth tier: 120x120 of interior behind an exterior that is still 16x16, with the Mk3's 32 connection ports in the same positions.

So a Mk4 drops straight into a slot you already built for a Mk3.

• Painted steel blue with "04" on the front, teal interior walls, its own map colour.
• Quality unlocks the same extra ports at the same levels — 46 at legendary.
• Works on space platforms too, as Space factory Mk4.

Two things worth knowing before you build one:

• The ports did not grow with the floor. 450 floor tiles per connection, against a Mk3's 112. Plan more internal bussing per port.
• 120x120 is the ceiling. It is the largest interior Factorissimo can generate, so this is the last tier at this exterior size.

Turning the setting off later removes the buildings. The interiors are not deleted, but the building is the only way in — so switch it off before you build your first one, or leave it on.

Factory logistics: outlet, inlet & sensor

Robots can't fly in or out of factory buildings. These bridge the wall by teleporting items across.

• Factory outlet — offers everything made inside your factories to the outside logistic network.
• Factory inlet — the reverse: fill it and it distributes into the requester and buffer chests inside.
• Factory sensor — interior stock as circuit signals.
• Fluid outlet and inlet — the same bridge for fluids, one fluid per device.
