Hello all,
can anyone tell me if this is really still within the tolerance range?
According to Bambu support (which rather leaves to be desired) seems to be still “normal”.
Instead, I get sent instructions to disassemble the thing itself … I thought I had warranty.

Anyway, this is noticeable when printing by loud “clacking” and also visually it no longer looks so great
How many hours on your print?
It could be noticeable on top/bottom infill where it has to jump back into place (like when there’s a hole and it needs to continue infill), but I’d say it’s not too bad.
Is the play coming from the bearing? I had a loose front chassis. Loosen the two screws in the back, remove the back cover, then tighten (don’t overtighten) the screews holding the front and back chassis, see if it disappears.
I have no idea how many hours of printing I already have, but it shouldn’t be many because I rarely print.
The problem comes from the bearing, but only from the bottom, the top is fine.
You can ask support againto send you a new carbon rod assembly, but I don’t know if this would have much impact on the prints - the nozzle shouldn’t actually be touching anything, and the weight of the tool head rests on the bearing so it will stay in place, also there’s two and there’s always some play in various parts. I also get buzzing and occasional click after having 4000 hours on the printer, but haven’t noticed any print issues, or rather those I’ve noticed ended up being cause by something else and usually just require a bit of maintenance.
But yeah, I get it, I would replace it too (or rather get a new carbon rod assembly and compare what is “normal”).
Care to share the photos of issues in the prints? I wonder how this would manifest in practice.
I was recently able to test a new Bambulab P1P (bought in June) that we use at work. It will certainly have run a lot more hours since it is in operation almost 24/7.
It’s normal for the plain bearings to need a certain amount of play, but for me it’s about 1-1.5 mm and that’s more than the comparison printer we have at work.
In my opinion this is too much play to manufacture precision parts.
