Coal Liquefaction in Factorio is modeled on the Fischer–Tropsch process , and this process is running with temperatures between 150–300 °C. Higher temperatures don't just yield more, it's producing different output. Usually even less desired output. Factorio's simulation should not leave its real wo...

Strategy considerations: - biters will come over and attack, if their nests are touched by the pollution cloud created by your factory and your mines. The pollution cloud is the red haze you see in map view. In case you deactivated the pollution view: enable it - to avoid biter attacks, either don't...

Have you ever been in a situation where you needed to restart solid fuel production without power? It's a daunting task, considering that a solid fuel production line relies on power, and the boiler consumes solid fuels to generate that power. This example is where a valve that operates without usi...

Anyone have something like that? What do you want to achieve in the end? If we don't know the whole task, it may be we're trying to solve an XY-problem while the complete task could be solved with a different approach that doesn't require a sticky signal. There is no built in method to make a signa...

From the FFF: https://cdn.factorio.com/assets/blog-sync/fff-402-rail-wires.png That's almost exactly how my rail blueprints look like - could have been a screenshot from my current factory :D I also added red and green wires "just in case a real use case pops up". I'm still waiting. The wi...

If you should use efficiency modules or not really depends on your game phase, intention, scenario, and the scale of your base. When I look at my just finished 2.5 KSPM base on a real map, energy usage of miners is negligible compared to the major consumers. There are no modules at all in the miners...

Problem #1) The Pump requires power to operate and requires separate isolated solar panels/accumulators to keep the pump and circuits working. Problem #2) The Pump requires an external logic circuit to perform something slightly more complicated than a simple boolean operator on a single fluid. [.....

I don't understand the purpose of 3 efficiency modules per miner. As far as I understand, one module is reducing power usage by 50%, capped at 80%, so 3 modules create 150% energy reduction but capped at 80%, so it's 80%. One module is completely cut away, and another by 20%. A more resource saving ...

And I will use whatever the devs choose as default, to stay compatible to what forum and discord calls it. And if it's "1st try", "trash", "mediocre", "refurbished", "ok".

This strange "S" grade system cannot be invented by engineers or technical orientated people, because it isn't following some intuitive scientific order of increasing importance or significance. Instead, it's arbitrary. There is no reason why an "S" is better than an "A"...

I strongly recommend using a one-direct valve, a top-up valve, and an overflow valve (available in mods and indispensable for better fluid distribution). This helps mitigate the downside of unpredictable fluid flows and less-than-equal junctions. This sounds as the vanilla game is lacking or insuff...

what are people's work arounds? You can ignore the finer details of fluid distribution, if you produce as much as or slightly more than your consumers are able to consume. But not less, because in this case one consumer will get all it can and the other(s) will get the rest. Don't design a setup wh...

I'm not familiar with hexadecimal Think of hexadecimal as an abbreviation of binary notation. To inspect the inner working of 32-bit integer arithmetic as it is used in Factorio, you will often want to write all bits explicitly, for example for 123456 you write 00000000000000011110001001000000 or 0...

In a comment to some earlier FFF I asked if there would be also some improvement to Nauvis to profit from engine enhancements made for the expansion. Many other games leave the original game completely untouched, so it becomes looking bland in comparison to the graphics detail of the expansion. And ...

I am quite late, almost exactly 2 years ago in 2021 I paid 25 EUR for Factorio 1.1 on Steam. It's probably the most valuable game purchase I ever did, so I will gladly pay the current price of 32 EUR, which is probably also near the price of the expansion.

Short of actual stats i made mock up graph Yes, that's exactly visualizing what I think about ore mine depletion. Of course the area covered by the graph is always the same, as it represents the amount of ore mined, and this is a fixed amount - the size of the ore patch. The ideal graph is a rectan...

As far as I understand the game mechanics, a miner randomly chooses one tile for one mining pass, randomly from all available tiles in its area. Since for overlapping areas there are multiple miners, tiles in overlapping areas are chosen more often, so these deplete first. If I speak of output in my...

Whether you use a higher or lower miner density depends on when you want to create new mining outposts. Your factory has some fixed ore demand. It doesn't care about miner density, it just wants to consume X ore per second. So if you build a mine with low miner density, the mine output is somewhat l...

I don't pull or push anything. Trains just flow between loading and unloading stations according to their schedule and free slots. The ore unloading stations have a static train limit of 4, so there is enough for a longer distance from the ore loading stations, and the ore loading stations have a st...

[resource patch size 60x60 / 40x40] Are those sizes accurate with patch size turned up to full? They are slightly larger. They have a few small branches or extensions extending the 60x60 area, but the general ore area is still within 60x60. If you want to know it exactly, create a map in creative m...
