Hello, I keep getting this filament powder clogging my AMS outfeed gear. At first I thought it was because I was printing with Creality ABS, but I’ve stopped and am still getting this clog. Im printing on an X1C. Any ideas?
I’m sure someone who knows better will weigh in, but to me it looks like some filament you were using may not be a good one to use in an AMS, where it needs to tolerate a little more friction than usual?
How much use did it take to end up in that state? I guess there was white filament being used? Maybe switching filament stopped it from getting worse, but the problem was already there and it was just some bad luck.
Maybe BL’s recommendation to use their filaments has some honest rationale behind it, and is not just a profit driven one. 
(I don’t know. But we have to question such things.)
Edit: I see there is an awful lot of it packed up where the PTFE tubes are. Whatever that might mean…
Oh, I’m misunderstanding aren’t I. You previously had this happen, cleaned up the mess (was it cleaned totally?) switch to BL filament, and this still happens?
Thanks for the reply @Lou
Now that I think about it, it’s actually not true that I’ve stopped using non BL filament completely. I stopped using Creality ABS, but I’ve been using quite a bit of Creality PETG (white)
Yes, this happened before around 4 spools ago, and I completely cleaned all the powder from tubes and gears. When I was done it was gone. Now it’s all back.
I’ve been using Creality PETG only because of the sales and fast delivery time from Amazon. I guess ill go with BL from now on as much as possible and see if that helps. You would think this would be a commonly reported issue if it is truly just from the Creality filament, but I can’t find a single mention of this issue anywhere… Really hard to believe this is only happening to me.
Yeah that is hard to believe. Hopefully someone with some experience using other filament brands can chime in.
I use mostly non bambu filament and that looks like the extruder gears are chewing into the filament and shaving off bits from the pressure.

most obvious to me would be that the ams hub is having to yank HARD on the spaghetti as it feeds prior to getting to the extruder, which tells me that the spool is not rolling freely or there are tangles or some such other confounding factor in getting the spaghetti off your fork. If that’s the case, try printing some tpu spool edge rims and/or checking the health and lubrication of the ams rollers

the filament was garbage town 5000 and throw it in the bin! If it flakes and powdered like that under normal op, you’d be able to tell from just yanking on it and raking your finger nails against it.

I don’t know if this is a typo or a joke I don’t get, but I laughed.
Now I need to think of how I can use “garbage town” in a joke somehow.
Sometimes the material is just ruined, garbage town 5000 is a real place [and it’s somewhere in Ohio /s]
I was trying to send thru old pieces of scrap filament collected from years ago (AMS lite is low key kinda nice for this) and came across a hunk of who-knows-what-PLA that was crispy, it just cracked every 2-3 inches if bent. It might have looked like this if it got into contact with the ams feed gear. </cool story bro>
