Any simple to understand guide to quality?
I am trying to start making better collectors.. But honestly have no idea how to do this. Other then throw quality chips in fabricator and cross fingers..

Not so much as a guide, but some general rules/knowledge:

  1. no mixing & matching different quality tiers on the inputs when crafting. If the assembler is trying to make "rare" collector, it needs "rare" (and only rare) inputs (blue chips, electric motors, LDS).
  2. You are 100% guaranteed to get the quality output item, as the quality-tier of the input ingredients
  3. If you add quality modules in the assembler: you have a "chance" to output items at a higher quality than the input ingredients
  4. speed modules hurt quality chances (generally) -- so don't use speed modules (or beacons) around assemblers leveraging quality modules
  5. post Fulgora: you can leverage recyclers, which themselves can be outfitted with quality modules. Recyclers will "delete" 75% of everything fed into them, however, adding quality modules will give you a chance at a boosted (higher) quality level on the parts the recycler spits out. Once you have enough of those quality parts: you can guaranteed make the higher quality collectors (#2 above).
  6. You cannot get a higher quality item, than the level you've currently researched. So if you've only researched "rare" level quality, you will never generate an "epic" item -- until you've unlocked Epic research. At which point your working base is now broken again, LOL.
  7. Fluids do not have "quality" -- all fluid is "normal" and can be used as input on any higher quality tier crafting
  8. Quality modules, themselves, also support quality -- higher quality quality-modules give you better odds.
  9. "unless you are using a mod, rocket silos cannot accept any quality ingredients above normal to make rocket parts." <-- wisdom nugget from @Material Defender in comments below

Hmm so i need to put quality chip on every part of setup. And research? I will need check that as no idea what level I have other then have the level 1 and 2 quality chips..
So i need to try upgrade raw materials.. and then upgrade intermediate parts.. to get better end products? I think i got it..

Quality has 5 tiers. Common, Uncommon (Green), Rare (Blue), Epic (Purple), Legendary (Orange) - you can't get higher than Blue until you go to other planets.

if you put quality modules in a machine, you get an RNG chance at the output being higher. If you have 10% chance, it's a 10% chance the output is higher quality than current. Each tier is also 1/10th as likely as the last one. So that 10% quality would be 9% chance of Uncommon, 0.9% for rare, 0.09% for Epic, and 0.009% for Legendary.


There's 2 general ways to do quality.

1. Craft Quality Items from Quality Components. This one you gurantee quality, but it comes at the downside of complexity. You would put quality on mining drills and smelters, and then from there you'll get quality plates to then craft quality with. This is more tedious as you'll now have to sort out and store the quality components and bring them to other parts of your factory - it can get clogged up and complicated really easy.

2. RNG Quality Items from lower quality components. - This has the advantage of simplicity, even if output is less guranteed. Just slap quality modules on your assembler making the end product, and it will have a chance to be higher.

The fun part is that you can combine both these methods together! Remember that thing I said above about each tier being less likely? If you still have 10% quality and you're starting from Rare, it's a 9% chance you're upgrading to Epic and a 1% of legendary!

Where this really comes into play is the Recycler from Fulgora. If you don't get the quality you want the recycler allows you to recycle some of the components to try again. Additionally, some items don't recycle into others (IE: Steel) - but they DO recycle into themselves. So a Recycler can be fed lots of regular steel with quality modules, and while most of it will be destroyed some of it will be "upcycled" and come out quality.

I think there are two main camps: 1) use quality modules along the entire supply chain, and shunt those special / lucky higher quality things over to long term storage until you've amassed enough to guarantee build whatever high quality thing that you are wanting to build. The longer the supply chain, the better your odds become.

2) or, forget the entire supply chain, and instead go straight for recycler quality loops -- called "upcycling". Basically mass overproduce collectors, and use quality modules only on those specific assemblers. Recycle/upcycle (with recyclers+quality modules) the vast numbers of "normal" collector's into their higher quality base parts.

BTW, I should add that quality modules, themselves, have "quality" -- higher quality quaility-modules give you better odds (will edit my first post to add that piece of knowledge).

Ok I had no idea how to get higher qualities. But now I understand.. each step you try to up quality. So far I can use 2 dot ones. 3 dot versions i need to research some thing. I have tons of bots so shunting stuff around isnt to bad.

Plus I have mod for trash.. and infinite ores. I love to build huge but hate having to keep moving so yes I cheat with these 2 mods.

But soon as I can i remove trash cans and pipe stuff back into factory. Until i get recyclers.
One thing you should also consider, unless you are using a mod, rocket silos cannot accept any quality ingredients above normal to make rocket parts.

Did not know that :-/


Question i have solid parts being upgraded.. But how do I do fluids?

Number 7 in the list: fluids do not have quality.
Ok i saw that but then when using un-barrel recipe i noticed quality... I thought it was quality of the fluid.. But its just the barrel. I confused myself lol

I feel like I may have just wasted a lot of time trying to get legendary stuff... Here is a very important bit of information that I missed and a lot of people may not realize. Not really a spoiler, because the information is available in game but is easy to get carried away by using the recyclers to grind quality and miss out on the opportunity for using quality modules on asteroid reprocessing when you unlock that technology. Here's what make the asteroid reprocessors so great.. Although you can only put two quality modules in them instead of four, they only destroy 20% of the materials fed into them before the quality calculation takes place. The recyclers immediately destroy %75 of what is fed into them before you even get a chance of getting upcycled components.

Oh now this is interesting. Thank you!
Legendary asteroids made into legendary sulfur and legendary carbon to make legendary coal. Take the legendary coal and make legendary plastic. Use the legendary plastic to make legendary Low Density Structures in a foundry. Recycle low density structures for legendary copper and legendary steel.

Legendary asteroids made into legendary calcite and used to make legendary molten copper. Liquid can't be legendary, but the stone that is a byproduct of the molten copper will be legendary. Use the legendary stone to make legendary bricks and concrete.

legendary asteroids made into legendary iron ore.

That covers most of the basic resources. Planet specific resources will have to be upcycled.
Im slowly getting there with your help
And I that was thinking Legendary Coal was a legend X D
KOS on YouTube did a pretty good look into quality. My key takeaway was that you have to visit other planets to unlock higher quality tiers.
