¶ Observation
This error pops up when the AMS internal hub hall switch is unable to detect the filament during the filament loading process.
Possible root causes:
- First-stage feeder abnormal
- AMS internal hub unit hall switch abnormal
- The filament buffer signal lost
¶ Troubleshooting
¶ Tools, Equipment, and Materials
Please refer to the info inside each detailed troubleshooting wiki.
¶ Fault Isolation Procedure
¶ Actions
Operators may use discretion in determining the actual procedures used, and the order in which these steps are applied.
¶ Step 1. Check First-stage feeder condition
The first-stage feeder may be abnormal, which also usually stops pre-loading from properly working. Please refer to the pre-loading failure troubleshooting section to restart the printer, insert filament for pre-loading, and then check if the functions of the first-stage feeder are normal.
¶ Step 2. Check AMS internal hub unit hall switch condition
After clicking "Load", the filament can be delivered to the PTFE tube on the back of the AMS, but the error that "failed to feed the filament outside the AMS" is still reported. This may be due to the abnormal internal hub unit hall switch being unable to detect filament, which is considered to be still inside the AMS. Please refer to the pre-loading failure troubleshooting section to restart the printer, and then insert filament to check if the hall switch is normal.
¶ Step 3. Check The filament buffer signal lost
When pre-loading and RFID reading are normal, the first-stage feeder motor does not respond after clicking "Load" and the error that "failed to feed the filament outside the AMS" is still reported, it could indicate an issue with the buffer. For troubleshooting steps, please refer to this wiki article: HMS_0700-4000-0002-0001: The filament buffer signal lost, the cable or position sensor may be malfunctioning.
If the issue persists after troubleshooting, please submit a customer support ticket.
