GregTech tech tree

[Heliomance]

We've just migrated our server world from DW20 to Ultimate. I'm in the process of making a new AE item processing/storage system, and I want to get the GregTech stuff integrated from the outset. GregTech is really quite complex though, and I'm not at all sure of what I need to be doing. What machines do I need, how many of them for a late-game auto-processing system, and what vanilla IC machines are rendered obsolete? And what do I need to be processing through the GT stuff?

Also, my new crafting room is currently a 21-black diameter hemisphere. Is this going to be large enough, bearing in mind all the multi-block structures involved in GT and the fact that I want to put in an AE autocrafter?

Power, incidentally, is not an issue. I have 22 Ultimate Hybrid Solars, and am eventually planning to build a fusion reactor.

I think few people can supply you a tech tree... Greg adds a new machine about once every two weeks at the slowest, which means everytime a FTB pack updates, all previous progression trees are invalid

The basic gist though is the trifecta of industrial centrifuge -> industrial electrolyzer -> industrial blast furnace. Aim for those three to be setup first, in that order. If you can, start with reinforced casings for the blast furnace, which will unlock most recipes right away (only tungsten will require more).

Then look into the wire mill, plate bending machine, circuit assembler, chemical reactor, automatic canning machine and the industrial grinder. It all depends on what is available in your current build (I honestly can't remember), and what you want to craft.

A gas turbine will give you good EU returns on the methane many recipes produce on the side. An electric crafting table will let you combine hydrogen and carbon cells (also common side products) into more methane without losing cells.

Oh, that's interesting for me too
Is there any guide on GregTech? It seems like it is better to watch current WayOfTime's LP to get into GregTech, but it's just work in progress so, "guide" is pretty slow ^^, he also went for Wiremill -> Industrial Blast Furnace -> Industrial Electrolyzer.

Yeah, you can build them in pretty much any order you want, depending on what you need. But most of the mod is based on the three core machines, and I listed them in order of building cost (plus you're not going to get much mileage out of your blast furnace if you have no way to electrolyze bauxite).

The main path of GregTech is usually someone saying "I want to build X", and then working backward from there to figure out what you need to build to make it possible, and what it takes to build that in turn. And I can pretty much guarantee you that no matter what you pick, at least one (and most likely two or all three) of the core machines is going to be heavily involved.

So there's nothing I need to build in from the get-go because I should be using it to process everything of a certain type?

Well, you can build the industrial grinder for the largest amount of bonus resources from ore in any mod short of factorization (and that only works for metals and takes ages, whereas the grinder works for everything you can possibly macerate). But it's not a hard requirement.

If you want to be fully effective, though, you should make a beeline for the rock cutter. It's a handheld power tool that comes with inbuilt silk touch. In fact, it can even silk touch a lot of things that the vanilla enchant cannot. Such as just about every mod ore that does not drop itself (gems, uranium, etc). And then when you go mining, silk touch all the things. GregTech adds maceration recipes for all these ores, which means you can now double uranium just like you can with metal ores. And if you use an industrial grinder (or to slightly lesser effect, a TE pulverizer), you even get bonus dusts on top of that.

And what do you need for the rock cutter? That's right: an electrolyzer and a blast furnace.

Extra tip: go into your thermal expansion config and enable recipe overloading for the pulverizer. Then GregTech will change the pulverizer recipes for five silk touch compatible vanilla ores (diamond, redstone, lapis, coal, emerald) from TE's basic "just convert them 1:1" into GregTech's "output doubling with bonus dust" model.
