Hello

I am trying to get a good main bus setup going. Can someone please link or list the ratios of different assembling machines for the various science packs? For instance, my understanding is that 3 assemblers doing copper wire can feed 2 assemblers doing green chips. Does anyone know good or optimal ratios for other items, such as inserter assemblers and transport belt assemblers for science packs 2? Blue science pack info would also be welcome, as would any other good ratios for any other common products.

Ideally, I am looking for the different numbers for different assemblers (grey, blue, yellow) as well as speed boosts .. but anything you have would be helpful

Thanks!

I can give some, but personally I think part of the fun of the game is figuring that stuff out for yourself. It's actually pretty straight forward.
For example; the gear assembler for Red Science if you are using the same level assembler for both the gear assembler and Red Sciences ones, then 1 gear assembler can support 10 Red Science machines. This is because the science takes 5 seconds, and gears take .5 seconds to make. Which means that in the time it takes to make 1 red science packs, you can make 10 gears. Each pack takes 1 gear, therefore it's a 1 to 10 ratio.

You can use the same approach for pretty much everything. It gets a bit harder if you are using different level assemblers for stuff since the crafting speed will obviously be different, but if they are all the same then it's pretty easy.

The few nice ratios that can be found breakdown once you start playing with modules. That's not to say they aren't useful for the earlier phases of the game, but by endgame, you can expect the numbers to never quite matchup. I 'solved' this problem by going to an all bot driven main base on my (now) longest played save. I let the bots manage all the moving around needed, and can keep scaling up the production on whatever I am lacking (I am also abusing Beacons pretty well with how I've laid things out).

For early game ratio purposes, I find it not that hard to do the math in my head as I play (but I am very good at mental math). There are some tricks that are helpful to the mental math, for instance, suppose you're trying to get the ratio of Sulfur Chem plants to sulfuric acid chem plants. Look at the recipes for both, since both are made in chem plants, they have the same crafting speed, hence things are a bit easier to math out. Look at how much Sulfur is needed per unit time and how much is made per unit time, find the ratio between those numbers (iirc, you need 6.25 sulfur/sec to feed one chem plant making sulfuring acid, and one chem plant making sulfur makes 2.5/sec, so that works out to a 5 to 2 sulfur to sulfuric acid ratio).

@Harkonnen604 Thank you, it was not exactly what I was looking for, but it is helpful

@Xterminator and @Frightning A bit less helpful. If someone is here looking for help, they probably don't need someone basically saying how easy the game is to figure out. Maybe just don't say anything if you don't feel like answering a question. I am glad you are great at math, but not everyone is. Some of us play for fun, not for the mental challenge.

I actually made proposal about that some time ago:

I think you missed a key point I was making: Only a few of the ratios are really worth using in actual gameplay (outside of megabase building where you need a plan in order to stay organized and actually get things done because of how massive that kind of base is), like the easy 3-2 ratio for copper cable to electronic circuits. The rest of my post was about how to figure a ratio that is important to you on the fly (I said it was easy for me, presumably because I am good at mental math, and proceeded to show you the way I think through it; which took me some time to come up with; this was not me saying it was easy in general, rather, easy for me).

for the science pack ratios i believe its 5 red to 6 green to 12 blue to 1 purple.
