### Red belt throughput

Posted: Fri Nov 23, 2018 12:16 am
So I found something interesting out. So I set up 10 Green circuit assembly machine 1s using the perfect ratio of copper wire to GC of 3:2. Since GC take 0.5 second to make 10×2=20/s. Mathematically this should fill 4/5 of a red belt as it has a throughput of 26.67 items/s, but it only fills 4/5 of one side This surprised me as I was trying to run throughput calculations for 4 belts of GC, so it actually takes in total 20 GC machines to fill 4/5 of a red belt.

The devs should make the note for belts 26.67 or 13.33 or 40 items/second/side just because I mean before now and I'm building a megabase i never even knew that

The error is in your production calculation not in the belt throughput though.

Assembler 1s take 1 sec to make copper wire, not .5 seconds.

The process takes 1 second in Assembler 1's, but you get 2 wires out of it.

No, it is 26.67 total items/s. Assembly machine 1s have a crafting speed of 0.5, meaning that 10 will make 10x2x0.5=10gc/s.

Also don't put copper wires on a belt. Feed it directly to the consuming assemblers.

For example for green circuit boards you place 3 assemblers for copper cable next to 2 assemblers for boards and 6 inserters to move the copper cables to get the perfect 3:2 ratio. Saves 50% of the inserters, the UPS for the belts and is more compact.

It's a good idea for anything with more output that input.

Just to be 100% clear - Belt throughput (both sides combined) is the listed number. Half a belt is half the number listed in the game.

Perhaps you will find this beltometer to be useful in the future. It is one of my most used blueprints when I'm designing stuff.

Clamp it to any belt to measure actual throughput.
The X=-1 constant combinator turns it on/off and resets it.
Output is on the red wire connected to the substation.

As others have stated, you did not take into account the speed of the machine making the GC’s. AM1’s are 0.5, which is slower than handcrafting. AM2’s are 0.75, which is 50% faster than an AM1, but still slower than handcrafting. AM3’s are 1.25, which is 66% faster than an AM2 and 150% faster than an AM1, and 25% faster than handcrafting.

Number_Machines*Machine_Speed*Recipe_Craft_Time=Desired_Output. Fill in the three you know and solve for the fourth. For any recipe, you know the Machine Speed and the Craft Time, that information is given in-game.

If you know how many machines you want to use, you can use this to determine their output. If you know you want to fill a belt, and want to know how many machines it takes, solve for that instead. Its simple algebra.

Or use hellmod to do the spreadsheet computations for you.

I have a hard time figuring that mod out, personally. So rather than recommend something I can’t really make good use of, and since he was trying to do the math, I decided instead to put forth the right formula.

LOL. I can't believe I didn't look at the assembler's crafting speed of 0.5.... Honestly, I never even thought about that.
