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..

Did you find a solution? I’m also see the same problems with my new AMS pros. Does it on all filaments, I’m having to vacuum out the ams after each print. The drive gears are really getting a lot of dust built up in them.
