- Additional printer-specific configuration options (depending on the driver)

FilaMan supports all BambuLab printers with an MQTT interface:

- **P1P / P1S** – with AMS (Automatic Material System)

- **X1 / X1C** – with AMS

- **A1 / A1 Mini** – with AMS Lite

When adding a BambuLab printer, the following information is required:

- **Host** – IP address of the printer on your local network

- **Serial** – Serial number of the printer (found on the printer or in the Bambu Handy app)

- **Access Code** – Access code (found in the printer's LAN settings)

- **Printer Model** – Model designation (e.g. P1S, X1C, A1) — determines whether AMS or AMS Lite is displayed

After a successful connection, FilaMan shows all AMS slots and their current contents:

- **AMS Slots** – Up to 4 slots per AMS unit (AMS) or 4 slots (AMS Lite)

- **External Tray** – The printer's external spool feeder

- Displayed information includes: filament type, color, temperature range, and calibration status

FilaMan offers two ways to send filament settings (material type, color, temperature) to a printer slot:

| Method | Description |

|--------|-------------|

| **Manual** | The user selects a slot on the spool page and sends the settings directly |

| **Automatic** | After weighing on an ESP32 scale, FilaMan detects insertion into an AMS slot and sends the settings automatically |

---

A spool can be manually assigned to a specific printer slot via the **spool detail page**.

- The spool must be linked to a filament

- At least one BambuLab printer must be connected (Status: Connected)

1. Navigate to the **Spools page** (`/spools`) and open the desired spool

2. In the lower section of the spool detail page, you will see a **printer slot overview** — for each connected printer, the AMS slots are shown as colored dots:

- 🟢 **Colored dot** = Slot occupied (color matches the inserted filament)

- ❌ **Grey dot with X** = Slot empty

3. **Click on a slot dot** — a context menu opens with the following actions:

- **"Assign spool"** — Sends this spool's filament settings to the selected slot

- **"Import to spool"** — Imports the printer parameters (tray index, temperatures) from the slot into the spool

- **"Import to spool & filament"** — Imports the parameters into both the spool and its associated filament

4. Select **"Assign spool"** — FilaMan automatically gathers the appropriate parameters (tray index, temperature ranges, material type, color) and sends them to the printer

5. On success, a **confirmation message** appears; on failure, an error message is shown

Automatic spool assignment allows you to automatically send filament settings to the printer after weighing a spool on the ESP32 scale, as soon as the spool is inserted into an AMS slot.

1. An ESP32 device (scale) must be registered in Device Management

1. **Weighing** — A spool is placed on the ESP32 scale → weight is measured and sent to FilaMan

2. **Pending** — FilaMan identifies the spool (via RFID or manual assignment), caches the filament data (material type, color, temperatures), and sets it as "Pending" on **all** connected printers

3. **Insertion** — The spool is physically inserted into an AMS slot

4. **Detection** — FilaMan detects the tray data change via MQTT and automatically sends the correct filament settings to that specific slot

5. **Completion** — After successful transmission or timeout expiry, the pending status is cleared

FilaMan compares tray fields (filament type, color, calibration ID, setting ID) against the last known values with every MQTT status message. As soon as fields in a slot change (= new spool inserted), the pending filament is automatically sent to that slot.
