Part Broke on AMS Internal Hub Unit

Bambu Lab AMS
1

Hello,
This morning, during a long print, the AMS was no more able to feed the filament in the extruder. There was also a very strange noise coming from the AMS hub unit.
So I opened the AMS and discover that the small plastic part holding the Wheel assembly broke (see pictures).

Do you know if this is a known issue?
Is it possible to reprint this small part, not the entire internal hub, just the small part holding the wheel?
pictures of the broken part.

Bambu Lab only sells the entire hub.

If that part is removeable, perhaps they can sell it to you if you contact support.

I have contacted support. They will have to replace the part.
But before they answer and send me the replacement I can not use the AMS. SO it is why I am asking if this small part can be reprinted and if some one is having the file.

Yes indeed it can be printed, but sorry I do not have this part designed, I would suggest you to try to design it (the whole part, including the four screw holes), also maybe you should lower the tensioner spring to avoid that to happen again.

Hi there,

For anyone in the future I was able to find this part to print.

Thanks for the info. I just printed a replacement after I discovered mine was broken. New one is working like a charm

Am in the same boat,only 6 months / 650 printing hours so am not impressed the part broke already. Will definitely try the print suggested.

Thanks for the link. Looks like a useful part

Two years later, still a weak point/flaw in design. In doing some reading, it appears that it’s possible they tightened it down too far at the factory. Thanks for the link to the STL for cover!

I just had to problem and this STL saved the day. Didn’t have to buy the whole assembly :slight_smile: Thanks.

Agreed. I actually ordered a new internal hub, before printing the piece and the piece came out of the package cracked.
