Ticking sound when loading filament ?!

Bambu Lab P Series
1

Hi,
The printer was printing just fine, and one failed print after at15%, I thought the supports may have displaced or I forgot to put supports in some over hangs areas.

so I tried printing another part at different orientation, and the filament didn’t come out of the extruder

As you can see in the video. I can hear this ticking sound, and the yellow gear tries to turn.

When I tried to load the filament. nothing came from the nozzle.

Could someone please tell me what’s going on. looks serious to me. I hope the printer isn’t broken

I feel so stressed out now , your help is greatly appreciated

Thanks a lot

Khaled

seems like there is some filament stuck in your extruder. I don’t even see the gear moving → that is where the sound comes from. it’s blocked. you need to disassemble the extruder. may have a look at the wiki for doing this. I will fetch the link for you:

you need to get the extruder out from the head and then disassemble it. it’s pretty simple. and no worries - your printer isn’t damaged.

Thanks a lot

Hoooeeee, it turns out I’ve just encountered my 1st clogged nozzle. I’m so grateful The nozzle was unclogged using the information and videos from this Wiki.

but Now I wonder if clogging could affect the gears, and motor of the extruder.

I now know that it’s unavoidable, but I hope it doesn’t reduce the life span of gears

Now I’m back to printing …

I’ve also did the cold clean method a few times

Thank you very much

yehaaa :slight_smile: :partying_face: the wiki really has a lot of information and already helped me a lot.

regarding the gears → you can buy the hardened ones (which are default in x1c) and switch to them if you have doubts regarding the lifetime:

Thank you very much for the advice, I think it’s well worth it

I’ve had hundreds of clogs (never print marble PLA). I’m still on my original drive gear after 2500 hours.

Sorry for the late response … I’m not very active in here … but this is really good to hear … I hope mine last as long …

Thank you

Mine is not the case.

It’s some ABS left in nozzle, but the Bambu remember it as PLA(Or someone do something make this.)

So it can’t melt the material as 200 that first machine try to purge old filament.

So what I do is skip that. Go into nozzle control and heat it until 300, and press down button let filament comes out. You also put different color PLA until it comes out.

After that just load what ever you want.

My X1C loads/unloads all filament at 250°C. If I use a high-temp filament like PA or PC one day and then PLA or PETG the next, the extruder may start skipping and fail to purge because the nozzle still has some old, unmelted filament in it. Keeping the nozzle at 250° for a few minutes longer or manually boosting the temp will clear the clog.
