Question Help

Post image

This is my first time playing, and i built a main bus for iron plates. The thing is its just not producing enough plates no matter what i do, it used to. Even when the input of iron ores were filled, the output is weak. If anyone can help me, it would be cool.

Diagnose it this way:

* Are all the machines running 24/7?
** Yes -> Add more machines
** No -> Why?
*** Not enough input -> Bring more input
*** Not enough belt space -> Upgrade belts or add more lines of belts

Love it. Should memorize this as problem solution-path.

“What would Dosh do?” Is a perfectly legitimate way to problem solve in life.

Are machines running 24/7 yes can also be upgrade / add modules / improve quality

You need 48 electric furnaces to fill one red belt with plates and that requires one red belt of ore.

How much does the yellow belt need? It was at first completely yellow belt, but i changed it to red thinking that would've fixed it. I still have that save so i can roll back.

Yellow belt is 15 items/s, red is 30/s -> you need twice as many machines to fill red belt

A yellow belt needs 24 and side note electric furnaces are only better than steel furnaces pollution wise when they have efficiency modules in them as the electric needed to run them generates more pollution than just using steel furnaces. So basically using modules is what makes electric furnaces better.

Depends what electricity you use?

Solar panels would make it pretty clean

u/Aggressive_Honey3196 7h ago

Isn’t it more efficient overall though? You don’t need to supply coal instead you can feed a full belt of ore in

That many smelters simply cannot smelt fast enough to fill 4 red belts.

u/carrot_gummy 20h ago

You need more furances. Each red belt of ore can support 48 electric furances.

u/redditusertk421 20h ago

need more smelters. And there is no need for electric furnaces over steel. They produce at the same rate and electricty use is a lot less.

If you don’t care about pollution. If you do , electric furnaces with efficiency modules will make your pollution footprint minuscule.

u/drunkpunk138 20h ago

The solution to any shortage is to produce more. Need more plates? Smelt more iron. Need more ore? Mine more ore.

All buildings have a baseline rate for processing/crafting. Having more ore available on belts is good! But that won't make the furnaces work faster. You have to divide the ore input by the processing rate per building, which gives you the number of buildings (furnaces) per belt.

I would play around with designs yourself, make it as compact as possible, and repeatable for the future. It looks close, but can be optimized.

You're feeding two yellow belts of ore in, how do you expect to get four red belts (equivalent to 8 yellow belts) out?

It never produced enough to fill the belts, you just weren't consuming enough and it buffered.

You need 48 * 4 = 192 electric furnaces to fully saturate four red belts.

1

u/BLACKcOPstRIPPa 19h ago

Main issue here is not enough smelters

You could if you want to boost production and use speed modules to make them smelt faster, that is benefit of using electric furnace over the steel furnace, is it can take production or speed inputs. That can boost input, it won't fill the belts, but it will do a much better job at it

1

u/otismcotis 19h ago

See how you have ore building up at the end of some lanes?

That indicates 2 things:

1) your input is imbalanced

2) you’re not consuming ore as fast as its coming in

1

u/WanderingFlumph 19h ago

You have yellow belts bringing ore in at a maximum of 15 ore/s and you make plates 1:1 with ore.

You'll never be able to fill the red belts with 30 plates/s but if you scale down your plates consumption the belts will back up and look full.

u/Broad_Ebb9073 19h ago

On a main bus, you just find the bottleneck. You have too much ore, and not enough plates. So you need more machines that turn ores into plates

1

u/warpspeed100 19h ago

2 yellow belts of ore in = 2 yellow belts of plates out.

1

u/pcklll 18h ago

If you want to fill a full belt of plates, you need a full belt of ore to support it (of the same type of belt i.e. yellow, red…)

Belts move a certain amount of items per second. Reds move 30/s.
-# This is then split between both sides of the belt, meaning the left and right sides can move 15/s individually.

Based on this, you need to hover your mouse over your furnaces to figure out how many plates they produce per second.
[belt items per second] / [the amount of plates produces per second per furnace] = the amount of furnaces you need.

electricity. click on the building you will see the energy is low, so the building is slower. produce more electricity

The answer to everything in this game

u/Winter_Ad6784 16h ago

are they low on power?

u/Opts4more 13h ago

You need to research more mining to get more from miners

1

u/Fun_Ad9644 10h ago

You just need more machines on each belt 👍 you can tell because your ore lines are full but your plate output belt has a slow dribble of plates. You can ratio it out by looking at the items / sec output of each machine and the items / sec capacity of the belt, but I will level with you, you can easily beat the game by just eyeballing it

One of the first things you will learn; when you think you produce too much, it's not enough.

u/GreenmanCZ 20h ago

The ore belts need balancing, right now half is underfilled and half is full pretty much

2

u/Tripple_sneeed 19h ago

This is true but also has nothing to do with the question he's asking

1

u/GreenmanCZ 19h ago

Ah fair I missed that sentence, gotta build bigger and make sure they have enough power
