Cracking Noise when printing

Bambu Lab X1 Series Troubleshooting
1

Good evening together.

I have a relatively new (only a few weeks) old X1C printer with AMS, which recently started making a clicking noise when printing.
But it is not the PTFE hose or the drag chain that scratches the glass.
I have also loosened the belt several times and tightened it again using the tensioners. But unfortunately that was just as unsuccessful as adding some lubricating oil between the flange and the plastic on the rear pulleys.
I have the impression that the problem always only occurs after a few minutes of printing, but never immediately when the printer is “cold”.
I’ve already opened a ticket with Bambulab, but so far they’ve only recommended putting some lubricating oil on the rear two pulleys between the flange and the plastic.
But as already mentioned, this didn’t bring any improvement.

I haven’t used the printer for many hours yet and I’m now disappointed because it doesn’t work properly.

But listen and see for yourself:

Does anyone of you have an idea where this noise could come from?
Because to be honest I’m pretty desperate

And i hope everybody could unterstand me, because i used Google Translator for help :wink:

Kindly Regards

I had a similar noise on my P1S. Just received it last week. It was the filament that was supplied with the printer. It seems like it was sticking to itself or the spool. Made a similar noise as it released. Small little cracks/pops as it unwound from the spool.

Maybe worth checking.

I have the same clicking noise at my new 10hours old P1S. I think it happens when Printhead/Chain moves back to the right rear corner. It looks like the (Chain, PTFE Connector/Holder) push at the Housing of the Printer.

Good morning,

@Gman
unfortunately it’s not the filament

@juergene
As I said, it can’t be the cable chain or the PTFE tube when I print in the front left area and the noise is also there.
The cable chain and PTFE are also “far” away from the printer frame

Hello,

i have exactly the same issue.
I’m now in contact with the support, but until now we haven’t a solution for this problem.
My Printer is a P1S and this printer is 6 weeks old…

I hope you gentlemen have found the answers to the clicking sounds in your printers. If not, get yourself a cheapie stethoscope and take the diaphragm, or even the head off, and use the end of it to locate the source of the noise. A foot or so of flexible tubing, like gum rubber tubing, could be added to the end of the stethoscope to make it easier to move around while the printer is making its noise. The closer you get to the noise source, the more distinctive the sound will be and you will find exactly where it is coming from. BTW, clicking sounds a lot like something dirty in a ball bearing. Hope that helps.
