HMS_0700_2000_0002_0003: The AMS slot1's filament may be broken in AMS
Each slot of AMS has two sensors to detect the position of the filament, one sensor is at the first-stage feeder and the other is at the filament hub,as shown below:
Some brittle filaments may break inside AMS and it usually causes the hub sensor at “ON” state and the feeder sensor at “OFF” state, and AMS will pop up with the message “…filament may be broken in AMS”, the light in this slot will also turn red.
"The AMS slot[n] filament may be broken in the PTFE tube."
The error codes below share the same issue as this one:
Please refer to this video to remove the broken filament:
