How to know which spool is in each Bambu AMS slot.
If you use multiple colors or frequently swap filament, it becomes surprisingly hard to remember which spool is sitting in each AMS slot. The fix is to rely on live spool data instead of memory.
Use AMS data, not labels on the shelf
A handwritten note or a rough memory of what you loaded last week does not hold up once prints, swaps, and reloaded rolls start stacking up. AMS spool data gives you a live picture of what is actually inside the machine.
Match slot data to real products
Seeing that a slot contains PLA is not enough. The useful layer is connecting the detected spool to an actual product such as PLA Matte Gray and then to the physical spool record that belongs to your inventory.
Keep unknown rolls visible
When a roll cannot be confidently recognized, keep it visible as unknown. That makes the workflow slightly stricter, but much more reliable for people who really want to trust what the AMS screen says.
