This is of course using belts, robots are probably more effective.
Pro:
- Uses belts
- Stackable vertically (beacons overlap)
- Compact
- Very high throughput (4x Productivity 8x Speed = 616% throughput compared to normal assembly machine without modules or beacons)
- Pretty good energy/item ratio (210 = normal, 2205 = only productivity, 595 = this setup)
- Uses belts
- Uses belt weaving
- Looks complex and messy
- Is complex and messy
