Most of these screenshots I took with a Vive using Vivecraft, so they're renders from the right eye, and sometimes have some odd masking stuff going on at the borders.
This is GT5U stuff, with almost all automation done with Magneticraft conveyor belts and inserters. I tweaked the Magneticraft recipes a bit to bring them in line with GT5U. So, for example, the inserters use GT5U low voltage electric motors rather than Magneticraft's electric motors.
Surface, which is almost entirely agriculture. The water collection system and water tanks are a highly visible exception. Stairs to B1 are visible in front of the rubber tree multifarm.
Workshop on level B1. All machines that I will likely interact with directly are on B1. Automated things that don't require direct access are on lower levels.
Ore processing. This is version 3 of the ore processing line. Unlike prior versions, it allows for any amount of re-processing, since all products get put on an output belt that cycles back to the start of the input belt. There's a chest buffer / inserter pair at the start designed to make sure stuff hits the input belt at regular intervals. This ensures that inserters grabbing things from the belt won't miss items because they're spaced too closely together.
All common operations work off this belt. Maceration, washing, centrifuges (thermal and simple), sifting, magnetic separation, electrolysis, and smelting.
Another view of the ore processing lines.
Dust / nugget consolidation on level B2. A ton of regulators feeding dusts and nuggets to packagers in groups of 4 or 9. Resulting items go back on to the input belt for possible electrolysis or centrifuging.
Blast furnaces 1 and 2. Furnace 1 has an oxygen feed. Furnace 2 is dedicated to titanium production, and takes a titanium chloride input. Both feed to the general processing belt.
Some products just as banded iron dust get automatically re-processed into furnace 1.
Vacuum freezer, partially embedded in the floor of level B2. The belt comes from the blast furnaces on level B1, and then returns to one of the output belts.
Steam boilers and steam buffer on level B3. The chest in the foreground is the input to the pyrolyse oven making charcoal. In the background is some gas storage for oxygen, chlorine, and carbon dioxide.
Pyrolyse oven making charcoal on level B4. In the background is the processing facility for excess sulfuric acid. Output is sulfur (conveyor belt) oxygen (green pipe) and hydrogen (red pipe).
