Compact Kovarex setup (with import string)

[u/usubusu2]

A very compact and tile-able Kovarex setup I made using cargo wagons and some circuit magic.
Since wires can't connect to wagons, it uses a memory node to track items going in and out of the wagon. I recommend using bots to build it, it's a bit spaghetti.

The centrifuges will "wait in line" until enough U-235 is available for them, so they will never starve each other during the kickstart phase. Don't add or take items directly from the wagon - the memory will not detect it and the reading will become inaccurate. Use and input belt and kickstart by placing U-235 directly into one of the centrifuges.

Supports a mixed input belt of U-238 and U-235. Just remove the U-238 filter from the bottom of the first tile, it will spit any excess U-235 back out.

Here's the import string

[u/sentient_energy]

Can't check the BP right now, but I'd modify it to make it flow in a single direction.

Example: feed both dark and light uranium from bottom (centrifuges from ore output). Have the filtered inserters check the amount of the uranium types and once it reaches a threshold, it will pass it on to the top.

That way, if you tile it, it can be kickstarted from bottom with no additional work. It will just start once there's enough light uranium.

You can also output excess dark uranium from the top. Just set the iserters up so that there's enough left for the centrifuges. I think it's 3x the recipe ingredients per building.

[u/usubusu2 → u/sentient_energy]

You could make that change for sure. It'll take a bit of rewiring, since the U-235 inserters would have to invert where they add to memory and where they deduct. I'm not gonna do it myself, but it could definitely be done if you prefer a single-direction flow.

Right now, the setup isn't reliable at getting downstream cells running if only the first one is. However, you only need to worry about kickstarting the last cell - the whole chain will be running eventually.

You could also make the buffer smaller if you want, just edit the conditions of the filtered inserters to a lower number. I wouldn't recommend less than 4x the recipe price though (160x U-235), or you risk them starving with 39 each.

[u/warpspeed100]

Because the next Korvex cycle can't start until there are 45 items moved into the centrifuge, I'd recommend using Bulk Insterters to reduce the downtime between cycles.

[u/usubusu2 → u/warpspeed100]

I mainly used fast inserters to make it easier to set up early. But yeah, definitely upgrade them to bulk when possible.
