During regular use of AMS 2 Pro, you can assess its proper functioning by observing the status of the LED lights.
This wiki article offers guidance on troubleshooting based on the LED light status, simplifying the process of identifying and resolving issues.
| NO. | LED Status | AMS 2 Pro Status |
| Error status (red light) | ||
| 1 | All four slots are flashing red light | Error status. AMS communication is abnormal, and AMS cannot be detected by the printer |
| 2 | Red light breathing | Error status. No filaments were inserted into the corresponding slots when printing start. It will return to normal after inserting the filament into the feeder |
| 3 | Red light keeps on | Error status. The filament is not detected by the feeder, but by the Filament Hub. It is possible that the filament is broken inside the Filament Hub |
| 4 | Red light single flashing | Error status. It may be that the slot failed to feed the filament, and the filament is detected by the feeder but not by the filament Hub. The filament is inside the AMS. Need to check whether the feeder is working properly |
| 5 | Red light double flashing | Error status. The slot failed to load or unload the filament. The filament is detected by both the feeder and the filament Hub. It needs to be further analyzed by combining the loading and unloading processes. |
| 6 | 4 slots red light breathing at the same time | 1. Abnormal state during drying; 2. When the drying module is idle, the NTC is disconnected, or the temperature of the air duct is too high. Check whether cables of each component are tightly inserted. |
| Normal condition (white light) | ||
| 1 | 4 white lights flash in turn | When AMS is powered on and initialized, the white lights will flash in sequence, and after initialization is complete, the four slots will remain on. |
| 2 | 4 white lights keep on | After AMS is powered on and initialized, or when the screen is awakened, all four slots have filaments inserted (the LED in the slot with filaments inserted will light up when the screen is awakened) |
| 3 | White light keeps on | The slot is in the process of pre-loading, reading RFID or printing (including loading and unloading). |
| 4 | The LED light is not on | 1. After the screen is turned off, there is no pre-loading, reading RFID or printing (including loading and unloading) in the slot within 15 minutes, and the white light is turned off; 2. When pre-loading or reading RFID, the white light will light up again, and the white light will be extinguished 10 seconds after the action ends; 3. After the AMS power-on initialization is complete, there is no pre-loading, reading RFID, or printing (including loading and unloading) action within 20 minutes, and the white light is off. |
| 5 | 4 white lights are breathing at the same time | Normal drying status |
