AMS 2 Pro - PETG Filament Shavings/Powder Around Feeder

[ezbsvs]

Howdy, I have two AMS 2 Pros, one on an X1C and the other on an H2S. I’ve been running green Elegoo Rapid PETG on both of them for about a month now. During that time I’ve noticed an increase in what looks like scraped filament shavings building up around the AMS Feeder Funnel.

I haven’t had an issue with any prints yet, but wanted to see if anyone else had a similar experience or any recommendations for avoiding this.

Thanks!

While this may not be the exact issue you have, check out this other post on this:

AMS is grinding filament, causing errors

During a 6 hour print with a lot of color changes over all four AMS slots, I get around 30-40 errors causing this to be a 20 hour print. [1672312328263] The error says: “Failed to extrude the filament, Please check if the extruder is clogged” When I go check at the printer and press “Retry” the AMS retracts the filament and I can see that the AMS has eaten chunks out of the filament, this causes burrs on the filament which can not pass though the AMS feeder, causing an error. [PXL_20221231…

It could also be that the filament itself is defective and has a larger diameter than advertised, which is 1.75±0.02mm.

@Kioto

filament itself is defective and has a larger diameter

This was my first thought also.

Did you ever find a solution to this? I am having the same issue with 2 brand new AMS 2 Pros where there is a lot of filament dust gathered around the filament intake on the AMS’s and also gathers in the 4 in One connector. It happens with both non-Bambu filament and Bambu filament. Everything is printing fine but after a few several hour print with multiple colors the dust gets everywhere, feeder gears and all..
