Find The Needle Automation Setup: Build a Line That Works on Its Own

Start With the Belt to the Sell Stand

The first automation you build should be a conveyor that carries hay from the pile to the Hay Sell Stand. It removes most of the walking from the early game, and community guides treat it as the first big time saver. Conveyors open once you have earned $100 and unlocked the build menu.

The Demo V8 update completely reworked belts, so they now snap much more easily and use automatic pathfinding. The conveyor also snaps directly onto the Hay Sell Stand. If a belt keeps snapping to the wrong machine, press F while placing it to switch on No Snap Mode.

Buy Faster Belt upgrades as soon as hay starts piling up at corners. Players report that tight corners are where lines clog first. A single speed upgrade is often enough to stop the back-up.

Power: Hay Generators and Power Poles

Rakes, arms and processing machines all need electricity. Buy the Electrical licence, build a Hay Generator, and connect each machine with Power Poles. The generator burns hay, so it doubles as a hay sink for your line.

When demand is higher than supply, every machine on the grid slows down together. In one playthrough every machine dropped to 63% speed until more generators were added. Since V8 the game shows a warning effect when power falls below the needed level, and generators can be levelled up when the grid cannot carry the load.

Two V8 controls help when you rebuild. Pressing E on a power pole shuts down the whole electricity network so you can move machines safely. Turn it back on once the new layout is connected.

Collectors: Rakes, Robotic Arms and Drones

The Hay Piston Rake pushes hay toward your line, and you set how far it throws so the hay lands on the belt. A wider head upgrade lifts it from 20 to 50 straw per stroke. Several upgraded rakes around the pile multiply your income quickly.

Robotic arms grab hay and drop it on the conveyor; at base level one moves 60 straw every 5 seconds. A tester measured roughly 3,500 strands per minute per arm at max level when hay is in reach. You can also tell an arm to pick up only clumps instead of loose hay.

Drones are part of the official automation list on Steam. According to the community wiki, a drone needs a licence plus a pickup, digs hay up to 12 meters away, and has to sit on the floor to work. Place them around the base of the pile within that range.

Splitters, Joiners and Feeding Generators

Splitters let one main belt feed several machines. The alternating splitter sends items to each side in turn, which is a simple way to keep a generator topped up while the rest goes to the sell stand. Demo V8 also added U-Splitters and U-Joiners for tighter layouts.

A common pattern is to split hay off the main line into one or two generators so power never drops. If the generator input fills up, the extra hay continues to the sell stand. Hands-on testing found that merging belts slightly reduces throughput, so keep merges to a minimum.

Scanners: Let the Factory Find Needles

The metal detector finds needles by hand, but scanners do it on the belt. The Prospecting Scanner checks strands as they pass and flags needles, and a Mark 2 version follows it in the tech tree. Footage of the Inline Scanner shows it catching a safety pin on the belt.

Place scanners on the main line before hay reaches the sell stand or a processing machine. That way nothing is sold or pressed into a bale before it has been checked. One player's demo build used about one scanner for every two arms.

Processing Lines for Deliveries

Once the basic line runs, add a processing branch for delivery contracts. A Hay Compressor makes bales, a Hay Wrapper wraps them, and later machines turn hay into eco bricks, pellets and paper. The Pellet Disc Machine shows resource indicators such as BRICKS and HAY since V8.

Put processing machines on a split from the main belt rather than in series, so a full output does not stop the whole factory. A throughput rule from the community planner applies here: the slowest stage limits the entire line. Upgrade the bottleneck first.

Upgrade Priority for a Faster Line

With limited money, spend it where the line is slowest. A useful order is belt speed first, then power, then collector upgrades, and finally more collectors. That keeps every new machine running at full speed.

Watch the power warning added in V8 and the hay counter in the corner of the screen. If the counter barely moves after a purchase, the upgrade did not hit your bottleneck.

Common Automation Problems and Fixes

Most stalled lines come from three causes. Check them in order before you rebuild anything.

• Low power — all machines slow down together; add or level up hay generators and feed them by belt.
• Clogged corners — buy Faster Belt upgrades or reroute with the V8 auto-pathing belts.
• Collectors out of range — move rakes, arms and drones closer as the pile shrinks.
• Lag in big factories — Steam warns that very large factories are CPU heavy; one player hit a limit around 20 arms.
