HMS 0700-2000-0002-0001: AMS Slot 1 Filament Has Run Out

HMS 0700-2000-0002-0001 means AMS1 Slot1 filament has run out. It is not a fault at all: the slot reached the end of the reel and said so. What matters is whether it happened in the middle of a twelve-hour print.
The useful question is not how to clear this message but how to stop meeting it unexpectedly.
Where to buy
Know what is left before you start
A digital hanging scale weighs a part-used spool in seconds, and the difference from the empty weight printed on the reel tells you the grams remaining. Compare that with the slicer’s estimate and you will never start a job you cannot finish.
Store part-used reels so they stay usable
An airtight storage box with a humidity indicator keeps a half-spool in the condition you left it. A reel abandoned on a shelf for two months is a different material by the time you come back to it.
Keep a second reel of the staples
For the colours you actually print, buying in twos costs the same per kilo and turns a run-out into a thirty-second swap. It is the cheapest insurance in this list.
Then set the slot up again
Load the new reel, confirm the material, and let the AMS run its own load cycle rather than pushing filament in by hand.
How HMS 0700-2000-0002-0001 differs from an empty slot
A slot with nothing in it at all reports HMS 0700-2000-0002-0002. Run out means there was filament and now there is not, which is a different state.
What happens next in a print
Mid-job the printer purges the old material, which is HMS 0700-2000-0003-0001. Multi-material behaviour is covered in multi-colour 3D printing and reel quality in the best PLA brands.
HMS 0700-2000-0002-0001 FAQ
Is this an error?
No. It is the slot reporting the end of a reel.
Will my print be ruined?
Usually not. The printer pauses or switches slots.
How do I weigh what is left?
Total weight minus the empty spool weight printed on the reel.
Can the AMS warn me earlier?
Only once the sensor sees the end. Weighing beforehand is the real answer.
