factoriolab VS FactoryPlanner

here's another: https://factoriolab.github.io/

Got everything built out for 500 spm using the online calculator (This one: https://factoriolab.github.io/) and when I was done I found a few issues.

https://factoriolab.github.io/ is the same but better than Kirk McDonalds in many ways.

I recommend the factoriolab calculator for satisfactory it's very powerful.

If you build everything correctly, there are no need to concern about the ratio of proliferator. Factoriolab is your friend to help you calculate how many of those proliferators are need.

Kirk's calc is superseded by https://factoriolab.github.io

To calculate the cost of burner inserters, I used 286 swings per coal (from my own testing), and then added additional mines to a factorio calculator to account for supplying the burners. Then I calculated the burner swings needed to supply the additional mines, and added even more mines to supply that, and repeated that process three times, after which the the tenth's place did not change. These additional miners providing fuel are not counted for useful output. I did not count the negative pollution from forestries.

(Or you can just use a site like factoriolab or a mod like factory planner to do the math for you and have perfect ratios anyway. The only wrong way to play is whatever way you don't find fun.)

Use Factory Planner to figure this kind of stuff out. https://mods.factorio.com/mod/factoryplanner

SE has quite complex recpies, especially for space science and processing of the new ores. I would have stopped playing a long time ago if it hadn't been for planner mods like Factory Planner ( https://mods.factorio.com/mod/factoryplanner ). I found Helmod's interface to be rather complicated so I mostly use Factory Planner even though I keep both around (Helmod provides some additional options like planning your build around the amount of available ingredients or number of crafting machines). With the "matrix solver" feature, you can plan a factory layout that produces the amount of materials you need and takes care of most/all byproducts. This makes the process of planning fun instead of tedious and then putting it in action and watching your new factory section go brrrrrr as it produces a new shiny thing for you to enjoy feels very rewarding.

Using a planner like YAFC, Foreman, Helmod, and Factory Planner is highly recommended. Also, the following mods are recommended for a megabase needed to finish a high-multiplier game:

FactoryPlanner or Helmod - Helps designing production chains. Quite complex at start, but well worth it. Factory Planner is the newer and cleaner design.

Factory planner. This mod allows you to plan out the production before hand (makes making everything pretty way easier as you know how many machines are needed)

Secondarily, you could use a mod like Helmod and/or Factory Planner to help you figure out how to make items. These mods are better focused for chains - i.e. breaking down an item (e.g. a science pack) down into smaller parts (e.g. ores), but they can also serve the function of letting you know which machine to use for which recipe.

I personally use the Factory Planner mod because it has some nice in-game features like automatic blueprints from the calculation.
