Why faster belt ?

[PotatoScav]

whats the pros and cons from it ? Is it alright to upgrade all belt to faster one ?

Faster belts mean higher throughput (items per seconds), so it's nice for the "main" belts but not really needed for the belts that just feed a couple machines.

The only real cons are the cost and that blue belts are too fast for yellow and burner inserters (they can't grab an item that is passing by without stopping).

Basically, when a belt is not enough to transport say your iron plates, you have the choice between having several or having faster belts (or both in cases where the needs are higher).

Some numbers to keep in mind, a yellow belt is capable of transporting 15 items per second (7.5 per side), red belts are twice that (30 per second) and blue belts are three times that (45 per second).

It is good:
when your output is overloading current belt.
When want to move more resources faster.
Want to keep end of belt "packed".

Some times for items with low resource cost. And long craft times. A slow belt is fine during crafting delay. As belt has time to refill. And it is cheaper to build those then faster belts. So saves on resources.

Fast belts good for longer distances, multiple factory buildings, and when output higher then belt. Like if have decent output but due to slow belt your craft buildings end up waiting on item need quickly.

for most coal transport for furnaces I will use 1st belt. For moving the coal to craft lines/factories I use 1st belt unless belt keeps emptying. Then I will add couple miners and upgrade belt.

Long story short... which belt to use depends on your current need. If lines stay backed up. You might get away with slow belt. But there are so many uses for each that is hard to say a definite yes or no. I suggest start with a slow belt. And then upgrade as needed.

Saturated belts are good for UPS, unsaturated belts are not, but this only becomes a problem after your base grows to a very large size.

I've found that they're useful when I'm trying to supply two arms with the same belt but one keeps snatching everything up. On the red belt the materials go by fast enough that this ceases to be a problem.

Of course I PREFER to solve the issue by backing up the belt with material all the way to the source but that's not always an option (except for with coal, it seems).

Factorio belts are pretty powerful compared to DSP/Satisfactory belts - they can support like 30 miners max so I would say stock belts are pretty good by themselves. Faster belts are only needed if you really wanna overload it with stuff for 1 single line, and even then you can just use splitters and after splitters you put basic belts

If you only have enough iron plates for one machine then the solution is to stop building more than one machine instead of wasting your time on these complex schemes which turn off the assemblers half of the time by forcing ingredient shortages.

Depends what final goal is. Some times I have a belt that run low. But works due to slow speed of another assembler or station. Though I prefer to have overfull belts. When a belt overloads and stops assembly... I dont mind it if its just for a little overload. As it lowers power usage for a min. As long as final product is steady.

But depending on how you build/setup your factories. Fast/slow belts... Full/sporatic belts.. all have their uses.

I don't want to keep a lot of belts types in my inventory, when some blueprints are using hundreds or more belts, I don't want a variety. Blue Logistics forever. Until a new color shows up.

[dragonsphotoworks]

set logistic for one stack of each. as use them up just run by logistic center and refill/unload as needed.

EDIT - In end i do it for all items I use. Evem ones i dont "i just set to trash them all". Then i just run by center and wait a min or two... then im back to start setting lol

I tend to forget about the upgraded belt types. The overwhelming majority of my construction ends up being just plain old yellow belts. Maybe the occasional red belt for the rare times I remember they could be useful, but blue belts pretty-much never get made at all, and only get researched to fill time while figuring out and building other science production lines.
