This morning I received the error HMS_07FE-8000-0002-0001: The lifting action is abnormal during the extruder switch. Please check whether the flow blocker is stuck or there is filament stuck in the toolhead.
No big deal I followed the wiki and checked all the recommended areas for possible cause. While I was in the tool head I found this little red lens caught in the flow blocker. What is it for, and should I be concerned that it is no longer attached to whatever it should have been?
