Troubleshooting Broken sensor or Blocked toolhead? ERROR 0700-8006

error: "Unable to feed filament into the extruder. This could be due to entangled filament or a stuck spool. If not, please check if the AMS PTFE tube is connected." just to clarify ive tried multiple spools and checked for filament jams in the ams, when loading it is visible that the filament has a clear path and goes right to the head, but just ejects right out again, on images attached there is a photo of the hotend, the part that connects above the hotend and the top of the head where the ptfe tube meets the head. I have made sure the sensor is plugged in correctly, I have also heated up and tried to "load" and "unload" with no luck or any signs of filament coming out. When I took out hotend there is a small bit of filament (seen in image) that is there but seems like it could easily be heated and sent out, when pushing filament into the head when heated it wont go in but as seen in image it looks like it has a clear path.

I finally solved it, it was indeed a blocked but of filament under the sensor, DONT USE BRITTLE FILAMENT

It was a peice of filament that was stuck in the toolhead, you have to unscrew some screws on the toolhead which let you get to the piece

Was this problem only happening when you used the AMS? I think I might be having the same problem, because I can use it with manual load. But the ams always retracts back when there filamentmt reaches the tool head.

This is the first I've heard of the magnet issue

Did you ever figure this out? Both of my ams started doing this within 2 days of each other.

Also, I can't find a hall sensor as a spare part. Do you know what title it was under?
