Combinator pls help

Hello there. i have just discoverd on google new nice and clever setup for the labs and i have made it, but there is a problem that i don't know the wiring how it could work and without it it doesn't work. when the inserter is putting into the wagon science it backups like 600 green and none of red and even it can't put no more green still tryes to put in more with it just makes a queue and the labs don't get all the science.. sorry for bad english. here's the pic and link for better explanation https://www.reddit.com/r/factorio/comme ... n?sort=old

Middle click each cargo wagon slot and give it a filter.

This.

That design doesn't need circuits.

i've already made middle click but still is putting the same science as is already full in the wagon

You can not use stack insertion if an inserter can reach more than one item type.

Just to clarify this point, if you look closely at Screenshot_23.png, you'll see that the inserter has a green flask in its hand. But the wagon is already full of green flasks. You either dedicate each belt to a single color, or you set the stack size to 1.

i could have set it to 1 item per stack but then it won't be enough fast for the labs. they'r gonna comsume faster than they can put in

how to i do 7 rows of science for 6 lanes long wagon?

The problem is that the stack inserter grabs up to 12 items, but when it can't put in all of it the rest stays in its hand and it can't put it back.

You may be able to get around this by limiting the stack size to a multiple of the available slots. 10 for example. But that assumes that it can always pick up 10 flasks. If the belt isn't fully backed it will fail again. Which is clearly the case here with all those splits
