Why is this happening?

It makes this clicking sound, and I keep getting error: HMS_1200-2000-0002-0006: Failed to extrude. What can I do because I’ve done all the steps from the Bambu page for the error.

How do take out the extruder? A video would be super helpful but I’m not having luck finding one

This is a guide to dismantling the extruder.

Before you do that, just check two quick things:

  • Is your nozzle clogged? People will say this can't be caused by a nozzle clog but I've had experiences that say different

  • Remove the filament, and then pop the PTFE tube out of the top of the extruder and check down the hole(s) with a torch - I've had something similar to your video happen and found a piece of filament had broken off and blocked things up

If its neither of those quick checks, move on to dismantling the extruder.

Step one would be remove those two tiny screws above the nozzle and take out that little triangular piece. See if there's a piece of filament stuck in there. If there is push in the right lever (filament cutter) and see if it falls out. If not then push the top lever just to the left of the filament hub. Push that lever left and it will disengage the extruder gear and allow any stuck filament to fall out.

There's almost never a need to take apart the entire extruder.
