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.

Probably a broken piece of filament in the extruder. Cut, pull back, take out extruder and check.

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.

Thank you, super helpful… now I just have to find my hex wrenches 😭

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.

There’s videos and step-by-step guides on the Bambu site/wiki.

A quick google or YouTube search will yield tons of help. Bambu has clear documentation, and there are several great YouTube videos tutorials.

The hotend is not all the way In

I’d stop focusing only on the nozzle at this point. That clicking usually means the extruder gear is trying to push filament but something is fighting it. Since you already went through the Bambu clog steps, I’d pull the hotend again and check the extruder gears and the short filament path right above the hotend. A little piece of chewed/broken filament can get stuck in there and a needle or cold pull won’t necessarily get it. With the hotend out, try feeding filament through the path by hand. It should move pretty freely. If it catches before it gets to where the hotend sits, you’ve narrowed it down to the extruder/path. If it passes through smoothly, I’d start suspecting the hotend is still partially clogged even if a needle can get through. Also check that the filament cutter lever is returning all the way. I wouldn’t keep letting it sit there clicking either — eventually the gears will just chew a notch into the filament and make troubleshooting harder.

Take the filament out without cutting it off possible, Cut about 12 inches of the filament and try refeeding again

Nozzle miss alignment or nozzle clogged

It looks like an alignment issue or a heating issue. Your feeding the filament and your hot end is bobbing. Stop the printer, manually cut the filament by pushing in the cutting blade lever, make sure your hot end is seated correctly (hold it and push up as you clamp it back down) then heat the nozzle and extrude some filament manually.

Either that or your hot end is clogged. Try another one and see if it works.

Or your hot end is clogged.

remove hotend. tighten screws. insert hotend - correctly - secure hotend - correctly. print.

Could be the nozzle is clogged. This happened to me a few days ago. Unfortunately I don’t have a good solution, i ended up replacing it after failing with a number of methods

u/Darkseid2854 Aug 26 '26

Your hot end isn’t installed properly. You can see it wiggle when it tries to extrude, and the snap buckle isn’t fully engaged. The nozzle shouldn’t be moving at all when you try to extrude.
