These damn mines are not grid centered. So i made one centred, you can rotate BP and it will remain the same.

Hm, what is even your use case where you need a 13 to 5 balancer?

In general, balancers should be used only in specific cases. In many cases they are not necessary or even hurtful.

Examples where you need balancers is offloading from a train with several cars, so that each car is emptied ...

I’ll leave in this post some useful pictures and links that I found which also helped to figure it out:

Thanks for the explanation and suggestions. Now I understand a little more, but apparently I won’t need the 13 to 5 balancer for now.

You might want to rearrange your smelter array to better fit output requirements instead of squeezing an uneven number of input belts to an uneven number of output belts. Balancers work best with powers of two as input or output belts, because with splitters you're multiplying belts with 2 or ...

I made a balancer by combining some other balancers together. Not the most elegant solution, but it works. For anyone interested in what it was needed for, here is the blueprint with balancer in it:

i think you could find a 16 to 8 balancer more easily, and then plug 3 of the outputs back as inputs alongside the 13 other lane.

16 to 8 is easier to begin with than 13 to 5 if you want to do it from scratch, and you can make it with 2x 8=>4 made out of 2x 4=>2

i would start by those 2x 4=>2 ...

Can anyone help design a 13 to 5 balancer
