U4GM How to Build a Cuprium Component Line for Arknights Endfield L70 Gear

 When you start aiming at Level 70 gear, you'll notice your old Xiranite-focused setup just doesn't keep up, even if you've got plenty of Arknights endfield accounts for sale options in mind for a fresh start or an alt run. The real wall is Cuprium Components, and the pain point isn't the recipe—it's the way ore and fluids love to jam up if you build it like an early-game line. What worked for plates and basics suddenly turns into stop-and-go production, and that's the worst kind of waiting.

Inputs and the core grid

Start with the inputs: Xiranite and Cuprium Ore. Lay four Depot Unloaders in a straight row. Set the two in the middle to Xiranite, and the two on the ends to Cuprium. If you've already got a dependable Xiranite line elsewhere, tie it in here and push it hard—around 120 materials per minute is the sweet spot so this rig doesn't starve. Drop a Gearing Unit directly below the unloaders and run belts straight down from the middle Xiranite unloaders into it. Then place two Refining Units, one on each side of the Gearing Unit, with a one-tile gap, both facing downward. Under those, place two Fitting Units facing inward toward the center so they can dump output neatly into the Gearing Unit.

Keeping items moving and power stable

The item flow is simple once it's placed right. The outer unloaders feed Cuprium into the Refining Units, refiners pass material into the Fitting Units, and the fittings push the processed parts into the Gearing Unit for final assembly. Route the finished Cuprium Components out into a Protocol Stash so you're not babysitting overflow. For power, don't overthink it: a Xiranite Pylon near the stash's lower-left and another near the upper-left usually covers everything in this footprint. If your belts keep stopping, it's rarely power—it's almost always fluids backing up.

Water in, sewage out, no bottlenecks

This is the bit people mess up. Refining needs steady water, and it produces sewage that will choke the system if you ignore it. Put a Conduit Outlet close to the Gearing Unit, then use a Pipe Splitter to feed both Refining Units evenly. Since the water source is usually far, place a Fluid Pump on a lake, power it, and connect it to a Conduit Inlet that links back to your outlet line. For sewage, place two Water Treatment Units right beside the refiners and pipe each waste output straight into treatment. They clear sewage fast enough that your refiners won't stall, which keeps your whole line from doing that annoying "runs for 20 seconds, stops for 10" loop.

Production pace and when to tear it down

Once it's powered and the pipes are flowing, you'll get a Cuprium Component about every ten seconds, so roughly six per minute—steady, predictable, and good enough for Level 70 crafting pushes. I treat this as a purpose-built rig: let it run until you've got a comfortable stockpile, then reclaim the space and Cuprium for your next project.
