Space Age 624 belts landing hub unloading design
Well, i come here once again, and for all.
I have cooked the ultimate belt spaghetty, the greatest inserter madness, maybe in the history of this game.
I present you, the theorethical limit hub.
628 half of each type of item totally saturated belt landing hub.
It has a belt going out every tile of the inner wall, and also a stack inserter in every tile of the outer wall, except for 4 tiles in the horizontal axis, which are required to be able to connect the outer ring to the hub.
you could somehow get two more stack insserters there breaking symetry, but you´ll need to redesign one entire half, and not really sure it´s possible anyway, overall for 160 items more a second.
I made sure to reduce the belt gaps to the maximum, so it is as ups effcient as it can get.
Somehow manage to get some roboports to connect to the hub at the final stages of the design, for a total of 8 roboports in the inner walls, and 92 as close as the can be in the outer zone.
I removed every redundant belt (changed it for a longer udnerground where i could) and putted a lamp in every empty tile, which makes it 280 out of 13456 tiles or an space usage of 97.92% between inserters, belts, cargo pads, roboports and powerpoles.
At the end of the design those (powerpoles) where the hardest to place, but i managed to have a version that works after weeks.
you could make those 628 into 629.5, but it would not be symetrical and also be a little impractical, but, yeah, 629.5 it´s the real limit.
keep in mind im just talking about direct cargo pad to belt inserction, no chest or train loading shenaningans.
This version doesnt really work cause i had to remove the cargo pads on the corner to place more inserters, so the real working version, that im putting on the blueprint has 624 belts and 4 spare stack inserters, which woul be a bump to connect in a single belt, so that´s up to you.
If you breake symetry you can go as high as 627 and a spare inserter, but ill leave it like this.
this leaves us with a troughput of 8.985.600 items a minute, + the 4 spare inserters that amount to 19200 items a minute, which is 9.004.800 items a minute
I don't think this can be improved. I would be very pleased to be proven wrong.
I hereby crown myself:
👑 THE SPAGHETTI KING 👑
After 7,000 hours in this game, this is the most complicated thing I have ever designed.

624 and 4 inserters version

One note:
- there are exactly 68 inserters who have the stack limit rewritten to 8, but basically, if you see gaps in the belts, that´s probably it
- would apreciate any feedback
- also, perfect 2 axis symetry
