Bambu Lab 0700-2000-0002-0001 on a 3D printer: AMS filament out
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Bambu Lab HMS 0700-2000-0002-0001 means the filament in slot 1 of AMS A has run out during the print. Load a spool of the required filament and press Retry on the screen, app or slicer to continue.
Safety first
Stop and check this first
- If you need to remove a piece of filament from the toolhead, do it with the nozzle cold: a 3D printer nozzle burns while it is hot.
Safe checks you can perform
- Which AMS and which slot
- Spool in the slot
- Load and press Retry
Leave these tasks to a qualified professional
- Do not attempt this professional task: After sales review if the alert stays
- Do not attempt this professional task: Check for filament broken in the toolhead
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
After sales review if the alert stays
What they doIf the alert stays with new filament, Bambu Lab support reviews the extruder filament detection and the path from the AMS.
They must show youwhat test they ran on the detection.
In writingcase number and diagnosis.
Check for filament broken in the toolhead
What they doThe technician or support checks whether a broken piece of filament remains in the toolhead and stops the new one reaching the switch.
They must show youthe clear filament path.
In writingwhat was found and removed.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Which AMS and which slot
- Who:
- you.
- How:
- read the full code on the screen and compare it with Bambu Lab's table: 0700 is AMS A, 0701 B, 0702 C, 0703 D, and 2000 to 2300 are slots 1 to 4.
- Result that matters:
- the exact slot.
- If it is the slot you expected:
- check its spool.
- If it is another one:
- check the job's colour mapping.
- Evidence to keep:
- photo of the code on screen.
Evidence: Bambu Lab Wiki: HMS_0700-2000-0002-0001: AMS1 Slot1 filament has run out.
Spool in the slot
- Who:
- you.
- How:
- open the AMS and check whether the spool in that slot has filament left.
- Result that matters:
- whether it is empty.
- If it is empty:
- load a spool of the filament the job needs.
- If it still has filament:
- note it for support.
- Evidence to keep:
- photo of the spool.

Load and press Retry
- Who:
- you.
- How:
- insert the required filament and press Retry on the screen, app or slicer, as Bambu Lab says.
- Result that matters:
- whether the print continues.
- If it continues:
- nothing more to do.
- If the alert returns:
- contact Bambu Lab after sales.
- Evidence to keep:
- time you resumed.

What it means
Bambu Lab explains this alert appears when the filament in a slot is used up during printing, that is, when the extruder's filament detection switch no longer detects filament. The code changes with the AMS and slot: 0700-2000 to 0700-2300 are slots 1 to 4 of AMS A, 0701, 0702 and 0703 are AMS B, C and D, and 1800 to 1807 are the slot of AMS-HT A to H. If the alert stays with new filament, Bambu Lab asks you to contact after sales.
Warnings and stop conditions
- Mediumeditorial warning
If you need to remove a piece of filament from the toolhead, do it with the nozzle cold: a 3D printer nozzle burns while it is hot.

Symptoms and causes
Probable causes · in order
- Spool used upCommon
Normally the filament in that slot has run out and the extruder switch stops detecting it.
Evidence: Bambu Lab Wiki: HMS_0700-2000-0002-0001: AMS1 Slot1 filament has run out.
- Switch not detecting filament that is therePossible
If the spool still has filament and the alert stays, the filament is not reaching the extruder switch; Bambu Lab points to its page on filament broken in the toolhead.
