Find the first machine that stops accepting cargo
Find The Needle conveyor belts blocked problems can begin downstream of the belt itself. Start where moving cargo becomes a stationary queue, then check the receiving machine's electricity, generator fuel, and processing speed. That is more useful than rebuilding every conveyor while an unpowered scanner remains in the way.
The fixes below follow recorded player experience, including a scanner that begins working after its power connection is completed. They are practical checks rather than a claim that every blockage has one cause. As checked November 3, 2026, the official Find The Needle Steam page still lists Early Access as planned for November 6; the supplied recordings retain their own demo-era contexts.
Check electricity and generator fuel
In the supplied full factory playthrough, wrapped bales queue at a scanner that has not been connected to the power line. Completing that connection starts the scanner and lets material move through. A belt reaching the machine is therefore only part of the setup.
Use this order of checks:
- Follow the queue to its first stopped machine.
- Confirm that machine is connected to the electricity network.
- Check whether the generator is running and receiving hay.
- Read the network's supply and demand information before restarting the line.
The same recorded player repeatedly finds generators out of fuel and later discovers that a growing factory needs more generation capacity. Those are different problems: a connection does not supply energy from an empty generator, and a fueled generator can still be too small for the connected load.
Increase scanner capacity when power is working
A working scanner can still process hay more slowly than your arms and rakes deliver it. In the recording, restoring power exposes a second problem: scanning takes long enough to create a persistent queue.
The player uses scan speed and batch-size upgrades, then divides incoming material among parallel scanners. Splitters distribute the input and joiners combine the checked output. These are supported examples of increasing the slow stage's capacity, rather than simply making upstream excavation faster.
After an upgrade, watch whether the backlog shrinks. A brief queue left from before the change is different from a queue that continues growing. Also inspect how traffic divides: building another scanner does little if most material still takes the original branch.
Avoid copying the recording's final scanner count as a universal recipe. Its required capacity depends on that player's machinery, upgrades, and layout.
Match the rest of the line to the bottleneck
Other recorded player experience includes a conveyor input reporting no room, hay missing the receiving belt, and machines producing more than the next stage can accept. Follow the material from one stage to the next rather than treating every symptom as a belt bug.
| What you observe | First check |
|---|---|
| Cargo stops at a machine that does not work | Power connection, generator fuel, and available supply |
| A powered scanner works but the queue keeps growing | Scanner speed, batch size, and parallel capacity |
| A rake throws hay onto the ground | Throw position and the receiving conveyor's location |
| Increasing diggers makes the queue worse | Capacity of the downstream stage receiving their output |
Make one adjustment at a time and feed the line again. Keeping the diagnosis local helps avoid spending on faster belts when the machine at the end is still unable to keep up.
FAQ
Why does my belt stop at a scanner?
Check power first. The supplied recording shows an unpowered scanner holding up cargo; it also shows powered scanners becoming throughput bottlenecks later.
Will a faster conveyor fix every backup?
No. Faster delivery cannot make an unpowered machine work or give a slow scanner more processing capacity by itself.
Should I add more generators or more fuel?
Check the actual condition. Refill an empty generator; inspect supply versus demand when fueled generators still cannot support the factory.
Can I remove scanners to clear the line?
The player does remove them temporarily, but later receives missed-needle sale warnings. Restoring scanning coverage with adequate capacity avoids accepting that tradeoff as the final layout.
