Fix that terrible squeak in your Bambu X1 or P1P

Is your Bambu X1 or P1P making a terrible squeaking noise when the bed moves up and down? Look no further this simple trick will save your ears.
All that is needed is a very light amount of synthetic (not silicon) grease on the upper edge of the belt - or the pulley - on the bottom of the machine. Super Lube is one of many products that could be used. Just ensure it's rubber-safe.

You are the best! Thanks for making this video :)

Nice tutorial👍

[@tha_factory_of_fun]

Hope it helped.

[@PimpinNProgress]

So clutch. Thanks bruh

[@IgorPomaranskiy]

Thank you so much!

[@adrianfaur7104]

Same problem. Solved. Thanks!

Haven't really heard of anyone else having this issue, but I feel like it shouldn't be an issue resolved with grease 🤔 (seems like something's out of alignment that's making the belt drift in the first place; only real issue with making something not meant to be modified, when something like that happens there's not much else you can do to resolve it 🤷🏿‍♀️) Good tip about the belt tensioner though, I didn't know it worked like that

[@tha_factory_of_fun]

Thanks for the comment. This solution was actually direct from Bambu Support 😊

[@TS_Mind_Swept]

@@tha_factory_of_fun Yeah, cause they didn't give you any other way to change it SuperVinlin
I mean I get they were going for a machine that you didn't have to work on yourself, but then when something like this happens and you will inevitably need to do stuff, you have to use workaround solutions instead of actually adjusting things that would fix the mechanical issue..

[@deltaphisig]

agree. they could fix belt tracking by puting a crown in the tensioing pulley so it will self align

[@Vudian]

@@tha_factory_of_fun bambu has put nothing out about using oil/grease on the belts and i dont see why they would, just a quick search and you will find out that the bests used in 3d printers will degrade if they have oil and or grease on them. if anything they would have told you to do an adjustment

[@tha_factory_of_fun]

@@Vudian Do you work for Bambu? if so let me know and I will give you the ticket number and you can see for yourself. Also, do you know the different types of greases/lubricants and which are rubber-safe and which are not? Before you make baseless conclusions that are wrong, you might want to do more "quick searching." I will also let you know there is an older video with over 10k views of people that this solved their problem and none of our belts have exploded. If you have facts, I am interested... theories, not so much.

Thanks. 👍

The same issue affects the pulleys at the top of the machine and the fix is to adjust the angle of the pulleys. I have not yet had a squeak on the bed but I would bet there is some way of adjusting that too. I would suggest adjustment is the correct solution to this issue rather than greasing

[@thegnarfox9487]

How to you adjust the angle of the pulley’s

[@AusMarineRobotics]

@@thegnarfox9487 I'm not sure there is a way to change the angle of the pulley. Saw another video about this issue where the fix was to reposition the actual belt to center it on the pulley. You need to loosen the tensioner first as described in this video first regardless of whether it is the xy or z drive belt. Think this misalignment of the belt on the pulleys is the actual cause of the squeaking problem which sounds pretty common on these printers.

[@AusMarineRobotics]

Thank You👍 - have seen a few videos about this issue which apparently affects the P1P, P1S and X1. This is the best (and the shortest). Also noticed some rubber scuff marks on your printer around 1:27. Looks like it could cause some wear on the bottom belt so keen to get your view on that.
Personally find it concerning that these pulleys and belts are quite exposed and could be damaged if anything got jammed between the bottom of the printer and the bench it is sitting on. Think my issue may have started after moving the printer on the bench to access the spool holder at the back - possibly misaligning that lower belt?

[@marks7626]

👌👍

[@rs3dpt]

Grease the pulley, not the belt.

[@kerplunk38880]

Absolutely never grease the belt. This is horrible advice.

[@tha_factory_of_fun]

Having an automotive background, I thought the same. This advice was Straight from Bambu. Note… this does not mean glob non-rubber safe grease on the belt, that for sure will ruin it. Have to pay attention to the details :) also I would love to know your rationale. Cheers

[@kerplunk38880]

@@tha_factory_of_fun Strange. They told me to lube the pulley and not the belt. Told me never to lube the belt

[@AusMarineRobotics]

@@kerplunk38880 Dont think lubing the pulley will do much as advised here the issue is caused by the belt rubbing on pulley lip. I think this guy is correct and noise is caused by a misalignment of the belt which occurs because the belt and pulleys are exposed. When you move the printer on the bench (eg. to access the spool at the back) it may dislodge the belt slightly if you are not super careful, causing it to misalign.

[@kerplunk38880]

@@AusMarineRobotics I respectfully disagree since I had this exact situation.

[@AusMarineRobotics]

@@kerplunk38880 So do I but think we might be both right here - lubricating would stop the noise by reducing the friction of a misaligned belt but it doesn't solve the actual problem (ie a misaligned belt).
