Ams Lite thinks there is filament loaded when there is not

Lately, my AMS 4 slot has constantly been purging filament randomly and stopping my prints because of the “filament tangled” error, though there is nothing tangled. I tried unloading my filament, but the slot still detects something. When I try putting in the filament again, it doesn’t “auto grab” it like the other slots. How can I troubleshoot this?

if you think its not a mechanical issue, hope its a software issue. Unplug, replug the AMS. Otherwise i’m not too sure

How do I fix it if it’s a mechanical issue? I think it is since before it broke I heard it squeak while printing

sounds like the filament broke inside. this is one way to fix

That link is for the standard AMS.

Here is the wiki page for the AMS Lite filament funnel which should give you enough info to take it apart and clear any obstructions.
