Yes you understood perfectly. As the combinator can read the speed and some people do it with some other calculators i thought it was possible. I'll wait for an update of the API
Thanks for your answer.

Hi, Sorry for my english, i'm not fluent at all :/ Well, i'd like to propose a feature to the mod, an option which could prevent to stop the manufacturing in progress if there a new recipe incoming or machine empty. I saw a solution with a timer and some calculation, but i'm not clever enought to do...

Mod : https://mods.factorio.com/mod/WideChests

1st version was a 2x600 chests long merged on 1 line, with smelting included
Multiplied by 18, with 4 lanes rail network.
Worked well ahahahaha

Next setp is 10kSPM with 100 modules

This is my first try for a 100SPM full integrated module with merged chest + LTN + Khagan solution. It's compact and pretty ugly,but it's work well. Next step is a 6 lanes rail network.

Thanks again for your help

Wow, i'm impressed by your responses !
I'm going to test all of that today (thanks to the quarantine) and i'll show you how i use it

Thanks guys !

Hi, Fist of all sorry for my english, i'm not fluent. I would like to transfer items from one vault to another using filters stacks + combinators for ease. I'm more or less able to do this, however if an item is missing, the transfer will be interrupted. That makes sense. I would like to change that...

Hi,just to inform, this mod is not compatible with Engame defense. It cause an error.
