Hi Guys,
I have this printer One week now,
After some prints , i start my first Multicolor print, but then i recognized some squeaking comming from the pulleys , at some movements of the printhead, what should i do now ?? Recheck the belt tension at the back?
I think the maintenance states that you should locate the squeaking pully and apply some of the lubrication oil onte the sides of the belt, as these are rubbing againt the “side wall” of the pulleys.
Yeah i was looking also this section, that maybe the belt could be dry at this section it is the left rear idlel that squeaking at the tensionier section.
Also i was looking to the lubricate tubes they are diffrent as at the manual , they had no great , how should i reach with that the back idler ? My Tubes has not the part i mark at the red section.
I see, my tubes look diffrent too.
maybe yould could move the head of the corresponding idler to either the max or min and just apply some on the belts, then move around as shown in the guide. Or apply some oil an somthing like a screwdriver bit, then apply that to the belt.
There are only lube and not oil at the maintenance package, but the main issue are the belt will rub at the rear Tensionier idler , so thats for me an allign issue . But you cant allign it , like on the p1p , because on the p2s the part are covered to see the idler. Also i cant understand at the back idler they used oil but in the inner side they used lube also .
I am having the same issue! I bought my P1S a year ago and still haven’t heard a squeak but I work in the P2s is already squeaky, not a great sign.
Bambu will say to you to lube them , like the wiki
Yeah I just did that and it did help.
But its only , making the Idler and belt get quiet, not the issue itself that the belts rubbing agains the idler
I wanted to share this is day number 2 of having the printer and the dreaded SQUEAK has started… I love this printer so far, except this… and so soon.
I am waiting for my P2S tool box insert to finish and I will address the idler lubrication that they are recommending; however, this is a short-sight on Bambu Lab IMHO… and very well a possibly a result of the ignorant tariff debacle this current corrupt US regime has put us all in - skip this if you have no problem with what I just said… if you still have a problem with it well = IDGAF and FYF if you think I have the TDS… it’s you MAGAts that do.
Either way, these printers sat in cargo containers or warehouses for too long OR the pre-shipment prep was not enough on Bambu Lab’s end OR this is an issue with current parts they put into these… or a mixture of them all.
I sure hope it is just the simple fix of lubricating the idlers. 
One can no longer call it a coincidence, as the squeaking is neither unique nor infrequent, just like the VFA (Vertical Fine Artefacts) issues that occur. It’s definitely a belt problem with the idlers. And the solution isn’t fixed by oiling them, as the belts still rub against the edge of the idler despite the oiling. Therefore, there’s a general alignment problem.
I used a fine paint brush which was actually helpful to spread the lube evenly across the belt’s teeth… this may help?
As I wrote, the noise disappears when you oil it. But it will come back when your belts are dry. there’s no point in oiling the belts, it’s not really the right thing to do.
Is it a bad idea to oil the belt? How much damage does both oiling and belt and not oiling the belt cause? I’m assuming its more than just dealing with the squeak, its probably going to wear on the belt over time right?
I did see this in one of the videos I watched before buying the p2s but oiling the belt seemed to fix it so I didn’t concern myself with it too much. But i also don’t love spending the amount I did on a product that squeaks, especially when it was a known issue on the previous model, which i only recently learned of.
