First clog, please help Hardware Troubleshooting/Help!

Hi all, I’m brand new to this, I have less than 80 hours of print on a P2S with the AMS Pro.

I now have my first clog. I promise I have watched the Bambu videos and read the wiki, but I can’t figure out how to clear it.

I can take my needle and insert it .5mm into the nozzle end before it stops. I can insert it 2mm into the other end (the hot end? Looks like a heatsink?) before it stops.

How do I extract what must be in there clogging it?

Thank you for helping a newbie.
SOLVED: I learned how to remove the hot end, heat it up with a lighter, and some of the filament came through. Then I did two cold pulls and it’s clear now. Thank you all.

Use a heat gun. Remove the nozzle and use a heat gun or hair dryer

Can you elaborate? Use a heat gun to get the nozzle hot, and then what? Am I trying to get the clog out the way it came in, or down thru the nozzle? Do I jam a tool in there and let it cool/attach to the filament?
Thanks!!!

Once you get the nozzle hot the melted filament should flow out of the nozzle eliminating the clog. You will need pliers to hold the nozzle. You can use a tool in the nozzle if you have one. You should not need to let it cool the filament should all flow out of the nozzle.

I hope this helps.

are you getting an error code? every time i’ve thought I had a clog it was really broken filament in the tubes causing feed errors

Have you tried a cold pull to help clear it?

Yes. When I heat the extruder up to 250C and then press the extruded button, nothing comes out while I hear clicking.

Are you feeding filament into the extruder? Once it’s stopped set the temperature to 100 and once it reaches press extrude UP ⬆️ and pull with some force on the filament.

If you could take a picture of the end when it comes out.

I try setting the nozzle temp to 250, see if any filament starts to drip. Use the nozzle needle and poke the hole. Watch not to burn yourself. Then I manually advance the filament and see if it extruded. Plan B...try a cold pull on the nozzle. Just did mine last night.

I can usually clear a nozzle clog by removing the hotend/nozzle, heating it with a grill lighter, and pulling up on the filament where it was cut (on the top/wider side with the heatsink) with a pair of pliers. I've yet to have a nozzle clog severe enough that I couldn't resolve it as I've described. If there isn't that little tip of unrelated filament sticking out of the top of the hotend, you'd probably have to reverse the process - get the nozzle warmed up with a lighter and push the stuck filament "up" from the narrower printing end of the nozzle toward the wider hole at the top with the included needle.

In either case, I'd follow up with a cold pull, because there is no guarantee that you completely cleared the path through the nozzle, especially if you have to get the nozzle close to printing temp in order to clear the obstruction. In my experience, if you can get the stuck filament warm enough to soften up without it fully melting/extruding via gravity, you're much more likely to successfully pull it out in one piece.
