Explain your problem.

Since 2.0, construction bots can refill the reactor, but you have to manually place a fuel cell ghost in each reactor to give the appropriate construction command (like for every construction). However logistics bots only interact with logistics chests. It may be possible with a mod though.

Another thing to consider, and which has bit me far too often than I care to admit, is that the enable and filters only work during pickup. If the train becomes full, or leaves the station, the inserter will complete its swing anyway and then wait to drop its hand contents into the next train that ...

I am still unable to build a ship which can relieably produce enough fuel for itself. Sooner or later, tanks will run dry an the vessel limps to its destination.

If that's the main problem (rather than asteroid defence), there are three ways of tackling it:
Reduce fuel consumption: thrusters ...

Indeed, you can have the C signal show up by adding an "Each(R) = C(R)" OR condition at the end. However then the output will be C+1, since you get 1 from the each output as well.

Use the "set recipe" option and stop sending any recipe signal. It will finish the current craft and then stop.

You're not comparing your signal to the constant value 4, but to the signal "4 on black". When you uncheck the "R" box, because there is no green wire, both "green check" and "4 on black" have the same value, zero. When you don't only "4 on black" is zero.

You'll want to enter a constant value ...

Interrupts only trigger when leaving a destination, not while flying. To stop flying to the shattered planet and return you use a fly condition instead. I'm pretty sure it's been like this since SA came out.

You should probably post a picture of your station schedule or a savegame so people can see ...

Pretty sure it doesn't work like that on Nauvis though, fresh expansion parties keep coming in from the edges of the already generated chunks, whether explored or not. So left to their own devices the biters will repopulate the world.

If this method works on Gleba (and is not a bug that gets fixed ...

This looks a bit contrived since you could just move one turn down a bit so they don't even touch.

How do you want the trains to move? One-way traffic or two way traffic, from where to where?

I don't think so. But there's two workarounds I'm using, (1) pick a ghost using Q on a legendary building, or (2) quickly Alt+Mousewheel to legendary quality. I've become accustomed to doing that while I move the mouse to the building to select so it doesn't even slow me down anymore.

If it worked before that would've been a bug, or you've been handling the items differently. Possibly you've been removing the items from the CLP so that they are immediately in the logistics network instead? Or maybe items just got removed quickly enough since the logistics network needed them ...

...or just press 'B' to drop in your blueprint book.

Congratulations!

Anything you'd do differently, as advice for someone else who wants to try this?

Not in the game I think (at least without mods), but you can look at the recipe.lua files, where ingredients listed with "ignored_by_productivity" are catalysts. However bacteria cultivation is really the only exception here.

Yes, in other words the 25 input oil is just passed through to the output, and 65 oil is actually produced and it's only this part for which productivity applies. This is the same for all catalytic recipes in the game (though mods could specify different ratios I think).

To add another related idea this makes me think about, add an inserter choice to pick up anything with specific spoil settings. For example, remove anything with less then a few minutes or percent left. Kind of like the spoil first/last but numeric which makes more since because stacks in chests ...

Your math is right, but you need to describe the actual problem more clearly, or post a savegame. Are the refineries running out of coal, or steam, or input oil, or not running for some other reason? Are you sure the belt is fully compressed? Are your inserters fast enough? Did you let it run long ...

About the 12 hour mark was when I had my first mobile space platform in my 40 hr run, so I think you're doing alright. Getting Nauvis done was the slowest planet by far. The next three planets took about 4-5 hrs each, and Aquilo almost 8 hrs because of all the supply runs needed, and researching and ...

There is now a cooldown between drops from orbit, so you will have to adjust your logic to account for that. But because of this perhaps you don't need that logic anymore and can just set the total number of items you want dropped instead.
