AMS 2 external hub squeaking

Bambu Lab AMS AMS 2 Pro

My AMS 2 is about 3 months old and today it started squeaking when printing. It squeaks when it jogs the filament. I’ve searched for instructions for lubrication but haven’t found anything. Anybody know anything about this?

Thanks

this happened to my AMS 1 and it was the A2 non powered roller that was squeaking I put some lube in it and that fixed it.

It’s not a roller that is squeaking it’s the external hub that jogs the filament.

I’ve had it. I put small amounts of grease on the end of the spring, that’s what’s causing the squeaking.

Thanks — but, what spring and how do I access it?
