I guess it may help to explain my ultimate goal which is to control rail signals (and soon to be train stops in 0.15) of a pair of same-name train stations. For simplicity I'll refer to them as left and right stations. I want the rail signal closed condition to be like this: Left rail signal closed ...

You can make it lots simpler, each-to-each combinators are your friends. I prefer green for "have" and red for "want" or "take" when I can get it, put one E2E×-1 combinator on your red signal, its output is now isolated from its input circuit so you can use any color y...

Water in/out seems also to have been changed dramatically - I have no idea how to stack boilers from 0.15 out The water only goes to boilers. You should be able to place them side by side like before and have the water flow through as many of them as you want. I don't know how many boilers can be f...

I have a situation with using both red and green color wires to create two similar networks. Each network is connected to a bunch of chests at a train station so that I can read the number of items inside, such as iron plates. So on the red wire I have an iron plate count and on the green wire I hav...

Hello, 1) If I buy the game on steam, can I download a non-steam version of the game on factorio website? 2) I heard steam fee is 30% of sale price, is it accruate? I'm not sure if that works, but I know for sure if you buy it on the website you also get a Steam key and would be able to access it i...

You can use the map editor to get a better picture of what the map settings do. After you generate a map in the editor you can scroll around to view a larger area so you know what to expect. Think of it as completely safe exploration as you can scroll way past the starting area and see the full layo...

I'm not very good at circuit networks, but I can manage a few useful tricks, including a few mentioned above. My latest is using the circuit network to open and close train unloading stations that share the same name. I have a pair of stations named "Iron Main" and if neither has a train p...

I'm curious about the space science. I totally love this idea, I just want to understand it better. Would this be just data transmitted down from the satellite and somehow magically distilled into packs inside the silo? Qute exacly so, I imagine the satellite transmits scientific data to the silo :...

Even apart from the fact that there is a new version release coming, this has to be one of the best made FFF posts you guys have done. Those graphics look amazing -- give those folks a raise! I'm curious about the space science. I totally love this idea, I just want to understand it better. Would th...

I haven't tried it myself, but I would guess that you need to increase the size of the starting area to give some space to maneuver.

There are probably a few things you can try. My advice may not be 100% accurate since I don't run my tracks in a similar fashion (my trains go the opposite direction so my signals end up on the outside of a pair of tracks instead of the inside), but here are a few ideas: 1. Try moving the southbound...

Actually our "design" is that repair packs should be put primarily to logistic chest (storage or provider) and slots in roboport are just for robots that are returning from repair job with some repair packs left. So putting repair packs to storage chest is preferred solution. :o I've been...

That's a good question I would like to know too. I would assume that the biters would want to attack you once they get hit with the pollution cloud, but whether they can is another issue. Of course you can just use some landfill to make a bridge across the water to the upper left and give them a nic...

TL;DR: Nightvision should be what it is: a nightvision. With that in mind I would like https://forums.factorio.com/download/file.php?id=19283 This is pretty much perfect This is by far the best version I've seen and really the only one that I would want to actually use in game. Greyscale is so much...

The downside to choosing to store as Solid/Rocket Fuel over fluid form is lost flexibility. If you suddenly had demand for LO or PG, you have to process more crude to fill it, whereas if you store LO and PG, you now have a reserve which could fill that demand without even needing to run your refine...

I think you're missing an important subtlety. What you describe is great if you have a nicely built factory that is producing at a fixed rate and hence has fixed oil product demands (in terms of crude at least). But if your demand is irregular due to backlogging (e.g. you make a certain thing faste...

In such situations I'd prefer to store everything as crude oil and stop refineries at all (it's easier to manage without tanks for HO/LO), and that's what actually happens when one of LB/PG tanks gets full. If you have enough chemical plants, you don't need any intermediate HO/LO stored at all. If ...

You don't need to have the same amount of throughput for the entire length of your main bus. You can start with more lanes and then whittle it down to fewer lanes later. Alternatively, you can keep the number of lanes uniform, but change the tier of belt you use. In my largish current factory I have...
