Creaking when Z axis moves

[JAAS]

Printer started making a weird “creaking” noise today.

I’m 100% sure it wasn’t doing it before, I started noticing it today and it’s very hard to miss.

Printer is less than a month old. Submitted a ticket but so far no response.

it took me some time but I was able to trace it here but have no idea what is actually causing it.It’s not the belt or the tentioner and to me it sounds like plastic agains plastic. Anyone knows having this issue?

Bambu Lab X2D Creaking sound

[JAAS]

What?

[JamboBambu]

If you do not feel free play in the pulley maybe some how related to the rod, or the other option something in the tensioner? Maybe you can try to get the Z rod from inside and see if you push it round if the sound comes from there. Maybe also not bad idea to cut the power when you do such trials . Does not look very hard to remove the pulley though.

Thanks for this. Removing the belt should prove helpful trying to pinpoint exactly where the pulley is rubbing

[JamboBambu]

Check the tensioner and the screws around. As you can just unscrew and screw it. It could be plastic but also some bearing noises, or bearing bed. Maybe something get lose because of this swinging of the whole unit.

Z belt squeak / scrape cure

Many people have the common issue of nasty sounds from the z belt when moving the bed up and down and especially during the homing function when it rapidly cycles. Every cure I’ve read up to now only addresses the symptom and not the cause, so here is my simple solution after replacing my z tensioner. The tensioner slides into a slot in the bottom housing that is very weak and has no reinforcement and this allows the tensioner to tilt off axis and cause the belt to ride up into the plastic hou…

Bambu Lab X1 Carbon - Squeaky noise when moving the Z axis

I have a noise on my X1C that is really getting me down. It is so unbearable that I am currently only printing with the A1. I’ve already turned the printer over and in my opinion the noise is either coming from the lower bearing of one of the Z axles or, more likely, from the belts that run over the pulleys/bearings. In any case, I had localized it down there with my smartphone and an app for measuring volume. In other forums I had read something about lubricating the backs of the belts, I had …

I saw that second one, that’s how I found the pulleys are down there. I originally thought it was on one of the front screws but twitch that post I narrowed it down to the rear.

Mine doesn’t squeal. Sounds more like “sand” in a bearing kind of noise. Maybe a busted bearing or something. The belt tensioner is pretty strong, I guess those bearings are under load constantly.

What really baffled me is Bambu response to the support ticket.

[JamboBambu]

You can see in other topics also Bambu replied like that if the printer is bought directly. Which is also the case with mine. So far I did not opened a ticket but who knows.

[JAAS]

I tightened the screw for the pulley I was moving in the video and it’s better now. It’s still not perfect and you can still hear some of it on long bed moves but overall when printing I can no longer hear it.

@JAAS
I got the same before and even worse. Because BambuLab is not selling in my country, they rejected from the beginning to send me any replacement parts, even I was still in warranty.

Luckily for me, my “reseller” was willing to help me out and sent me the replacement part for free.

@JAAS

What?

[JamboBambu]

Yeah they seems to have some notes in the warranty:

I think support just jumped to the conclusion that replacement parts were required hence the redirect to your reseller. Just answer the ticket that you don’t think part replacement is required but you simply need some technical support to fix the issue. See how it goes, BL should not disregard technical support and if in the end a part replacement is required under warranty then and only then the reseller is the point of contact.

[JAAS]

They did send me the link to the video that was already shared here about the z axis pulleys.

I tightened the screw for the one shown on my video and it’s better. At least I can’t make the noise by moving it anymore.

It’s somewhat noticeable with long bed movements but under normal printing (bed barely moving) seems fine

[philch]

Glad you fixed it. I was under the impression BL support did not respond at all, good they provided instructions

[mannyu33]

The noise is coming from the tentioner rubbing or pushing away the plastic mount that holds it , I had this exact problem as well and removing the tentioner mount solved it, I tried tightening the screws and it made it worse, releasing the bolts 1/4 of a turn helped, eventually I greased the spots when there is plastic on plastic tention and it helped

[JAAS]

In my case I could feel it directly on the pulley when moving it like in the video. And it did made it a lot better when I tightened the pulley screw.

I’ll check the tensioner you mention to see if that eliminates it 100%

Adding my experience, as I was also experiencing that issue. I was able to solve it by simply tightening this loose screw:
