Can you help me identify what is happening here?  

RE: Can you help me identify what is happening here?

What kind of filament are you using?  It looks so raggedy after coming out of the nozzle... is it possible it has absorbed too much moisture, and is breaking off in the bondtech gears?

Don't panic. This isn't a big deal.

1. Raise Z up (press and hold front knob) so you can work easily.
2. Heat to the printing temp of the last filament you used.
3. Open the extruder door and look around inside with good light.
4. If you see filament wrapped around the Bondtech extruder gear (I don't see any in the video, but it can be on the other side), pull it out with needle-nose pliers.
5. Inspect the white PTFE tubing below the extruder gear. Do you see any filament sticking up below the gear? If so, try to grab it with tweezers or needle-nose pliers.
6. If you can't reach it, use (ideally) a 6in/15cm 1.5mm rod (available from hobby shops) to poke in from the top filament feed. You can use your hex wrench in a pinch, but it's not very long. Poke down past the (open) extruder gear and into the PTFE tubing. Support the extruder assembly with your free hand and avoid any twisting, then press gently down on the rod/wrench to see if you can get the filament down into the hotend. If using the short wrench, press as far as you can then push in some of your stiffest filament. With any luck, whatever's stuck will extrude out the nozzle.
7. If you can't push the blockage out, raise nozzle temp to 285C and remove the nozzle. Read up on this. You MUST support the heatblock with a 16mm open wrench (ideally), and use a 6mm socket (ideally) for the nozzle.
8. Try pushing through again. You can also push from below to see if anything pops up out of the PTFE tubing where you can grab it.

While you're at it, swap in a new nozzle just to be sure. Keep the old one, it can be cleaned out (read up on cold pulls), but a known-good spare is a good idea for troubleshooting.

If these steps don't work, you might be looking at an extruder tear-down, but I haven't had to do one for a very long time.

Read up on cold pulls and be sure to do some especially if you switch from high-temp or filled filaments to lower-temp regular filament (e.g. PETG-PLA).

ah there is sound in the video... didnt work on my other pc.... that does sound like you might have a jammed ptfe tube.  I'd try what bobstro is saying.  You are fortunate that you still have plastic coming out the nozzle.  I had a hard-jam in my tube and had to replace it completely.  You can probably push it through after letting it warm up a bit...

Sorry it took me so long to reply to you guys. Been out of town for 2 weeks. Out of sight, Out of mind. Now that I’m back I need to get my printer up and running. I’m going to give your suggestions a try. I’ll let you know how it turns out.

it has absorbed too much moisture

It isn't necessarily what is causing the problem, but the filament is quite wet. It has all the symptoms of it once extruded. Moisture is boiling in the hot filament. I know because I have an issue with this constantly and I'm yet to come up with a definitive dry box solution.

bobstro, your list of steps was awesome! It worked. I followed your steps, one by one. There may have been multiple areas that needed attention, but in the end, I ended up replacing the nozzle, and now I’m back in business.  Thank you so much.

And next time the jam happens, do a normal UNLOAD, and keep the stub that comes up.  It can be very helpful diagnosing the cause of the jam.
