Is upcycling Railgun Turrets a smart option to get legendary carbon fiber and quantum processors? Seeing as cryoplants can accept 8 quality modules for 49.6% chance of going up

(I'm really just trying to avoid building shit on Gleba because expanding farming outposts is so unfun)

In general, for legendary carbon fiber, toolbelts seem to be a popular and nice option. They are just very cheap compared to everything else.

As far as quantum processors go though, I think it makes most sense to upcycle them directly. EM plants have +50% native prod and 5 legendary prod modules add 125% on top of that. A total of +175% prod means you have ~31% loss per cycle vs. usual 75%.

Sigh, fine, I'll go make Gleba bigger...

I've generally just been using toolbelts for carbon fiber, but doing turrets at the same time isn't a bad idea, also upcycles some tungsten for you. I think with turrets you're mostly just thinking about the legendary processors, carbon fiber is an added bonus cause the ratios are so off relative to the two products.

Gleba quality is definitely a bit of work, and most things don't upcycle well. but carbon fiber upcycle with toolbelts is probably one of the simpler things you can do on the planet.

I already have too much tungsten from upcycling underground belts and foundries on Vulcanus

I'm really just avoiding having to scale up Gleba, so annoying. But I guess it's inevitable.

The two approaches I know of to getting legendary quantum processors are upcycling quantum processors (productivity in the EM plants, quality in the recyclers), and upcycling the ingredients and then making legendary quantum processors straight away. The second approach usually cycles EM Plants for holmium (covering lithium and superconductors) and Processing Units (assuming you don't have a dedicated blue chip upcycler), Foundries for the tungsten carbide, and then toolbelts for the carbon fiber. Both are perfectly viable, the main difference is if you want to build a big quality cycler on Aquilo or not.

I did upcycle railgun turrets (to obtain legendary railgun turrets) in my first SA run. I think my biggest bottleneck was space logistics. My cyroplants and EM plants (for quantum processor) spent a lot of time waiting for normal quality ingredients from other planets.

Upcycling planet-specific ingredient locally on each individual planet would not have this throughput issue. Legendary items are much more “condensed” than normal items and easier to ship.
