¶ Overview
¶ Description
During extruder switch, the lifting motor moves the left hotend up/down, coordinating with the flow blocker. If movement fails, the printer pauses and reports an error.

¶ Root Cause
- Deformation of the flow blocker
- Jamming of the lifting mechanism
- Left hotend clog
- Filament clogging in the extruder
¶ RC#1. Deformation of the flow blocker
If the flow blocker is deformed, it can’t switch properly below the hotend. Replace the H2D nozzle block. If paused, resume printing.
¶ Actions
Action1，必须保证与Airtable上的一致；格式及一致性的脚本检查。
Action2
¶ RC#2. Jamming of the lifting mechanism
¶ S1. Manually swing the flow blocker left and right.
¶ S2. Try to resume printing if the printing was paused.
¶ S3. Try manually switch between the left and right extruders if the printer was idle.
¶ RC#3. Left hotend clog
¶ S1. Press the left cutter to cut the filament.
¶ S2. Disassemble the hotend, clean any foreign objects.
¶ S3. Try to resume printing if the printing was paused.
¶ S4. Try manually switch between the left and right extruders if the printer was idle.
¶ RC#4 Filament clogging in the extruder
¶ S1. Disassemble the quick change tool interface.
¶ S2. Use scissors to cut away any deformed filament, disconnect the PTFE tube, and manually pull out the filament from the toolhead.
¶ S3. Check if the filament is stuck in the dual extruder filament guide entrance or internally. If so, clean it.
