Not every machine should run constantly. Redstone-responsive transmission blocks make factories switchable, reversible or synchronised.
Control roles
- A Clutch can disconnect rotation under redstone control.
- A Gearshift can reverse rotation when activated.
- Use controls for doors, gantries, processing modules and any system where stopping safely matters.
Safety
- Expose manual stop controls near moving contraptions.
- Test reversing machines with empty inventories before putting valuable items through them.
Readable routing
- Use service corridors, gantries or underfloor drives so each branch has a purpose.
- Ratios and reversing components should be near the machine they control or clearly labelled.
Maintenance
- Design around access for a wrench and goggles.
- When a branch fails, test from the source outward rather than changing everything at once.
Routing motion
Transmission determines whether a factory remains readable. Straight shafts make strong service spines, belts combine transport with visual motion, and gearing belongs where its direction or ratio change is easy to identify.
When a machine must be switched, reversed or speed-controlled, put the control where the operator can see the effect. A control room is useful only when the controlled system is comprehensible.
Troubleshooting order
Start at the generator and follow rotation outward. Confirm each branch turns, note where direction changes, then inspect the consumer. This method is faster than randomly replacing gears in a crowded mechanical room.
