Do you hate routing circuits into each other? I do. Do you hate that every time you expand one of your circuit builds you have to reroute half your base? I do. Do you just want a build you can just copy over and over no matter what circuits you are running low on? I do.

The IDGAF productions systems proudly introduces it's first and latest creation the Circuitron 3000 A tilable circuit builder that builds all the circuits simultaneously so you never have to worry about using different BP-s for any one of them.

Does it use perfect ratios? No. I don't even know what it supposed to build at any moment, how am I supposed to optimise for ratios?

Is it a particularly efficient use of buildings? No. Do I care when all it uses are stuff I can make for free? (and calcite, technically) Also no.
Is it an efficient use of modules? No. But it makes circuits. What do modules take? There you go.
Is it good on Fulgora? Just use bots. It's Fulgora, that's the point.

Known bottlenecks:

1. It's build with the experimental new feature, where you can chose the output side for inserters outputting on parallel belts, but i don't play on experimental, so you will have to add that in for yourself.
2. Theoretically, on higher quality tiers, the inserter inputting the iron into the Gchip EMP can prove lacklustre, I never really dabbled withe quality. This could be counteracted with higher tier inserters, not sure if after upgrading the plants, the modules and the beacons that's gonna suffice. What you can do is use fewer lanes for GChip output, I honestly don't know how much GChip you need once you don't have to use them for other chips so I kinda eyeballed the three output lanes.
3. The build is "optimised" for using these level of modules, and bildings, but it works pretty well with lvl2 prod modules the it gets somewhat iron plate starved. You can just slap on one extra pair of beacons
4. The amount of molten copper and iron use depends the use of the outputs, I used this triple pump setup because it lets you build 40 row of this without issue and 40 almost nets you two full lanes of redchips which is what I always bottleneck myself on. If you need more fluid inupts just move the iron plate smelter to the right. Although at one point you will reach 46 width, at which point it will no longer fit into a standard roboport grid.

Constructive criticisms are always welcome, this build hasn't been tested in a real base.
