All Lights blinking Red, One faster than the rest

Bambu Lab AMS Troubleshooting

My AMS 1 is currently not working. I had filament in Slot 4. I removed the filament as you do, as then the whole AMS started blinking red. Slot 4 blinks faster than the rest. I have unplugged it and plugged it back in, I have let it sit unplugged for an extended amount of time, I have opened the AMS and looked for filament in the tube underneath it. I have run filament from the opening through the tube.

I have no idea what I should try next. I recently replaced the motor on Slot 4 due to the old one not working. After I replaced it, it worked fine. Not sure if it is related.

I have looked around for the error of one slot blinking faster than the others but haven’t been successful.

Thanks.

4 red lights is an error state, AMS communication is abnormal. Here is the wiki page for diagnosing this issue.

One slot blink faster may mean that there is filament stuck in that slot.

I have run filament through the line, and nothing appears to be stuck.

The filament switch might be stuck.
