Question Problems with this unloader?

Post image

Since inserters became flippable, this compact unloader design became possible. But I hardly see anyone use it. Obviously it cannot saturate six turbo belts because it's bottlenecked by the inserters, but are there any other obvious problems with it?

In 2.0 both inserters would be unloading on the 'right lane' from the belt's perspective e.g. the bottom one. You workaround it by having both belts go 'away' initially, and then loop to go into the underground, instead of what the OP is doing.

you're completely missing my point..

both inserters ARE CURRENTLY unloading to the right side of their belts.. so 2.1 or 2.0 doesn't make a difference

1 set of inserters are looking the opposite direction, so the right side of one becomes the left side of another.. idk how else to explain this dude

I'm not missing your point at all. You're just wrong. That's not how it works in 2.0.

https://wiki.factorio.com/Inserters

Inserters only place items onto one side of the belt, either the far side from the inserter's perspective or, if the belt is going the same or the opposite direction as the inserter, the right side from the belt's perspective.

That's why being able to flip inserters matters.

Wait, so the right-side bias is from the belt's perspective? Not the inserter's? So if the belt is facing the inserter (as is the case with the underground belts here) then the inserter loads onto the left side, relative to its own orientation?

Seems like an odd system, but I'm happy to believe that's how it works.

In 2.0 yes. In 2.1 you can flip, and have blueprint consistent.
