How to build

  1. Drawers first: nether stars, shards, energized shards, one drawer per infused shard type (4), TNT, and a drum per molten powder (blaze, blizz, blitz, basalz). Every machine has its own input drawer behind a Modular Router or Pipez item pipe with an Item Filter and a Keep Exact Robot Arm on the output. — functionalstorage:oak_1, minecraft:nether_star, kubejs:nether_star_shard, minecraft:tnt
  2. HV Forge Hammer: 1 nether star → 5 nether star shards, 15 s at 240 EU/t. One drawer for stars; the first star is the only one you ever feed by hand. — gtceu:hv_forge_hammer, kubejs:nether_star_shard
  3. EV Polarizer: 1 shard → 1 energized shard, 20 s at 960 EU/t. Dedicated machine; Keep Exact 8 on the output so the autoclave always has shards. — gtceu:ev_polarizer, kubejs:energized_nether_star_shard
  4. IV Autoclave (3840 EU/t): energized shard in the bus, 720 mB of ONE molten powder in a fluid hatch, 48 s, 0.95 shards on average. Use one autoclave per element (four machines) or one autoclave with one drum at a time: a Modular Router with an Item Filter would otherwise mix the elements. The output stays the element of the powder: blaze → fire, blizz → ice, blitz → lightning, basalz → earth. — gtceu:iv_autoclave, kubejs:fire_infused_shard, kubejs:ice_infused_shard, kubejs:lightning_infused_shard, kubejs:earth_infused_shard
  5. Molten powders: LV Extractor, 1 powder (blaze, blizz, blitz or basalz) → 144 mB, 22 ticks at 30 EU/t. 5 powders per autoclave run. The powders come from the elemental chain (blizz, blitz, basalz) and from blaze powder. — gtceu:lv_extractor, gtceu:blizz_bucket
  6. IV Forming Press: the star casting mold in a non-consumed slot, then 1 fire + 1 ice + 1 lightning + 1 earth infused shard → 1 impure nether star in 15 s at 7680 EU/t. Wire the press with an input bus that holds the mold in a slot and an Item Filter on the four shard types. — gtceu:iv_forming_press, kubejs:star_casting_mold, kubejs:impure_nether_star
  7. Implosion Compressor (EV hatch, 960 EU/t): impure star + explosive in the input bus → nether star + 25 % dark ash in 1 s. The explosive: 4 TNT or 1 industrial TNT per star (GT industrial TNT is the cheap one). Route the new star back to the hammer drawer through a Robot Arm: that closes the loop, while a second Item Filter route skims stars for the radon chemical bath. — gtceu:implosion_compressor, minecraft:nether_star
  8. Easy to miss: every star you divert to a quantum star is gone from the loop. Count stars, not shards: at 1.19 per pass the loop only sustains a star drain of about a fifth per pass. Build a backup stock of 4 infused shards per element before you start emitters and sensors in bulk. — gtceu:quantum_star, gtceu:hv_chemical_bath

Tips

  • Source: kubejs additions/progression/lines/nether_stars.js. Hammer: 1 nether star → 5 nether star shards, 300 ticks, 240 EU/t. Polarizer: 1 shard → 1 energized shard, 400 ticks (20 s), 960 EU/t, which is above the HV 512 V, so it is an EV Polarizer; the old node said IV.
  • The shard autoclave: 1 energized shard + 720 mB of the molten powder → two independent chances, 50 % and 45 %, of one infused shard each, 960 ticks (48 s) at 3840 EU/t, so an IV Autoclave (3840 is above the EV 2048). On average 0.95 infused shards per run. You need 4 different ones (fire from blaze, ice from blizz, lightning from blitz, earth from basalz), so 4 energized shards and about 4.2 runs per star.
  • Impure star: IV Forming Press with the star casting mold (shaped: ball casting mold + file) in the not-consumed slot, 1 each of fire, ice, lightning and earth infused shard → 1 impure nether star, 300 ticks at 7680 EU/t. Implosion Compressor: impure star + 4 TNT (or 2 dynamite, 1 industrial TNT or 8 powderbarrels) → 1 nether star + 25 % dark ash, 20 ticks at 960 EU/t (an EV hatch).
  • Net yield: 1 star → 5 shards → about 4.75 infused shards → 1.19 stars. The loop grows by roughly a fifth per pass, so it is NOT free: every quantum star (emitter, sensor, field generator) eats a whole nether star. Keep the first star out of the loop until the IV circuits and the hull line are ready.
  • Alternative start without shards: 8 charges (fire, ice, lightning or earth) + 720 mB molten powder → 20 % of one infused shard, 720 ticks at 960 EU/t in an EV Autoclave (kjs). Charges: mixer, coal dust + gunpowder + the powder → 3 charges (100 ticks, 30 EU/t). That is 40 charges per infused shard, so only useful when you have lots of powder.
  • The Heat Chamber (energized molten powders) and the nether tempered routes in the same script are LuV and ZPM recipes: ignore them at IV.
  • Per star the powders are small: 4 × about 760 mB molten powder, i.e. 4 × 5.3 powder items. One craft of the powder reactor gives 16 powder (see the elemental chain). Quantum star: 1 nether star + 1250 mB radon, HV Chemical Bath, 96 s at 480 EU/t.
  • Sub-steps people skip: (1) the shard is polarized in an EV machine, an HV polarizer does nothing; (2) the autoclave takes the powder as a FLUID (extractor from the powder item), not the powder item; (3) the forming press mold must not be consumed from the input bus: leave it in its slot; (4) four different infused shards: a drawer per type with Keep Exact 4, so one type does not pile up while another is missing.
  • Unverified where blaze powder comes from (the pack removes the vanilla recipe and the Create crushing of blaze rods; a GT macerator recipe was not checked), and the first nether star itself (it is in the one-off items list, vanilla drops).
