Hello people.
After 1800h of printing a squeaky metallic sound appeared when Z hop is happening.
I did a maintenance to linear rods, pulleys on XY same as carbon rods. I also lubricate the door at the back which pooh goes in cos it had a weird sound when was moving. The sound is still here and cant locate it.
Any idea would be appreciate.
You have a squeak when the Z stage moves, and you did all the maintenance except the Z rod clean/lubrication step?
Take care of the Z axis stuff, since that’s what’s making the noise.

ofc i did maintenance on Z too…But as mentioned the sound comes when Z hop and not when moving the bed up and down from screen or slicer. It seem that little hop gives the squeaky sound but cant locate it.
For Z hops, the platform isn’t moving very much, the jack screw is only doing a fractional amount of rotation. The noise has to be coming from the Z-stage, nothing else is moving.
Besides lubricating the screws and rods, there are also bearings at the top of the screw shaft. Those might benefit from a small drop of light weight oil. There’s also some rubbery grommet things there, too. If those are moving, they might squeak, rubber-on-metal.

Thanks for your help. I applied some drops of super lube synthetic oil(ptfe) on both bearings on the top of the two front shafts. The one behind is difficult to access it. I will start a print with z hops and check.
So how did that turn out? I am assuming you were able to fix the problem. These threads always have people troubleshooting and then there is never a post if they resolved it or not and how they actually went about it.
I am having the same issue currently and have oiled the front two shafts… still a squeak.

To be honest oiling the shafts didn’t solve the problem. I didn’t reply with a solution because i don’t have a solution. The squeaking sound gone but not from lubing. I tried the following and maybe one of this might be the solution.
- Lubing the shafts and bearings.
- Opened the extruder and cleaned it. There is a spring there for the tension of the gears. When z hop, the extruder retract so i gave a clean.
I had a squeaky/squealing Z-axis and traced it back to belt rub on the tensioner pulley underneath (at the back side). I suspect that the adjustable nature of the tensioner makes it easy to tilt relative to the belt and as a a result the pulley ends up riding against the flange.
I “solved” it with a drop a grease on the flange, but I wouldn’t consider this a real fix as the grease will just dry out eventually and it’s not exactly great to get grease onto the rubber belt either.

I have the same problem. Doesn’t Bambu Lab itself speak up here to present a solution for it?
nope, they always answer with a “lube the belts or lube everything”. I learned to live with it and no more supports tickets. At least they should ship the printer with a jar of lube.
Try to locate the sound and if its on the tension pulleys just apply a drop of superlube ptfe on the outside of the belt and wipe it with a ear cotton stick. If its squeak when z hop then check ur rods or the tension spring inside the extruder. At the moment these are my feedback after 1.5 years with X1C. Hope it helps.

Pretty much what I had to do too … turned printer carefully on side, lubed every single flange - top and both, I used a very long bambu pointy stick (giant tooth pick) to just get a tiny bit on the upper and lower flaanges, and then moved the belt around to spread it.
I also felt the belt edges - and soem are defintely more “rougher” than other part of the betl edge, proabily just cut like that, but I very carefuly and lighly lubed those areas and my squeaks finally went away for about a week now.
I figure its about 30mins for a full service evvery month\1000 hrs print… not a big deal to do the “Z” betl tensiors\flanges as well , after doing a full lead screw clean and re-grease, carbon rod clean, belt tension check etc etc. IT adds maybe 5mins to the whole maintanence routine.
PS . I didnt like using a q-tip\cotton bud - leaviing cotton fibres etc (or at least my brand does along the sharp flange edges), but each to their own boat.
Yep, that where I traced it to also. But I can’t seem to get rid of it. It is super evident when (after homing) lower the bed by tapping the down button several times.
i have an open thread for it aswell…In my case something was caught inside the Z bearings. I cleaned the rods and applied a drop of superlube oil straight to 3 bearings. After some hours it stopped.
I’m having similar issue… it makes a timed chugging noise in the background when i raise or lower z axis. is it something wrong with my printer? or is this normal? do i need to oil something? Video:https://photos.app.goo.gl/MKdMgHiwJqpT4LDQ6
Sounds normal to me. The sound i was talking about its like i described. Unless you didn’t catch it with mic.
got mine a few days ago and today after 30horus on this one print i notice it… im a newbie but i imdidialy saw it was when the z hops lol also ive been printing it for 30 now and the sound only comes up once in a while … but still a solution or a fix would be needed if this happens more often!!! i also got it on video i will post it here in a bit…
Did you make the video?
at the end when the door is closed u kind of hear it clearly… almost sound like clicking but its squeaking… it almost is gone now i just hear it once in a while… but today also a new squeak showed up -.- was alot louder… it came from the left side in the back… def need to do a mainentacne in the coming days… im scared to print like that…
