If you use quality modules in the miners and load all qualities into a train, you get every possible combination of item and quality, even if you don't need them. In addition, ratios are wrong. You get everything with a chance of better quality, but you need only part of that. It might be better ...

The trains are doing mixed-cargo on Fulgora. They have 1 stations that is a generic 'loading' station:

What exactly do you mean with "mixed-cargo"? Do you mean you load multiple material into the same train at the same time, or do you mean the same train loads and carries some item for one trip ...

I am at a point of running all across my factory putting off fires for half of the time. I destroy one nest and another nests attacks me on the other side of the factory, almost constantly.

You need to automate biter defense. Factorio is an automation game, so it's no surprise this kind of a new ...

You didn't set a train limit, so as long as this station is enabled, all trains will path to it since it's the nearest station. No matter if there is already a train sitting at the station or not. A station is considered occupied only if there are train limits set and this limit is exhausted because ...

You have a weird spacing, but I guess this is what you're trying to achieve. Rotates and mirrors perfectly. Mirror only possible of course without rail signals.

In my opinion, this request can be closed, because it is obsolete.

About the inventory: It's now possible to request bots into the roboport. You can read the bot statistics. So to balance bot amounts in the network, you request a small amount of bots into one roboport and read bot statistics. You ...

I can't help but cringe a little when I see setups with tons of Beacons and SP-3's with no EF-3's at all and think to the authors of such things: "Have you ever considered your energy spendings?"

Yes, and no. We all try to optimize our factories, and it seems there are different optimization ...

Please don't remove ANY as output for the decider combinator in general. There is a valid use case, for example for auto malls. You want to filter a set of signals from a huge amount of signals by matching them with EACH, then get one of them for the mall to craft with an ANY. The decider combinator ...

Move one of the concrete lanes 1 tile to the outside or to the inside. It's probably not equidistant to the center but instead 1 tile mismatched.

Check the description of your mod called "peaceful nauvis".

Does that in 2.1 mixed fluids is possible, or does that mean in 2.1 the fluid system is better protected against (accidental) mixing of fluids? Bidirectional fluid boxes are not as isolated as they should be, as far as I remember.

I made an extendable design that minimizes the effort for extending and rebuilding the smelter line. Of course it includes the steel furnace, because it doubles throughput on the same layout. No upgrade is easier.

1st design is for the early game and contains 24 stone furnaces. Consumes/produces 1 ...

Nice, it works! However, I see the main point of this forum section not only to simply post an image or a video of your creation but to do a presentation of your creation. A presentation will include information about how it works, so your readers will understand how it works and are able to include ...

For asteroid reprocessing, I specifically made a post on discord that uses the lookup table concept in a single combinator:

It doesn't use EACH to directly determine the asteroid chunk with the biggest amount ...

What is the round trip time? And how big is the promethium storage?

I tried to optimize the round trip time with the platform I made and was able to make it about 1 hour. 30 minutes there and 30 minutes back again and it produces 15300 promethium science in that time.

It loads 8500 biter eggs in ...

In general is there a raw amount of inputs to the factory that I should be aiming for to build a "big factory?"

For example, presently I have 4 belts of iron, 4 belts of copper, 4 belts of uranium, and 4 belts of stone coming in. These belts are fed by multiple electric mines at various ore sites ...

Didn't see it before elsewhere: clamping some value to an upper limit with a single combinator.

[L]=value to clamp
[M]=upper limit

But, in my opinion, the game doesn't really start until after you've launched your first rocket, and then have to figure out how to build a (big) factory.

The game has definitely 2 distinct parts: the 1st part is until launching the first rocket, the 2nd part is building a really large factory ...

I've noticed if I have more heat exchangers that it seems (maybe I'm wrong) to both take longer for the core to reach maximum temperature and longer for it to drop in temperature. Is that accurate? I would then assume that it doesn't really matter how many exchangers you really have or don't have ...
