I've got an AMS Pro 2 that I've had for about a year. I've printed maybe 25 hours in total on my printer with this AMS connected.
As of right now, 2 of the four slots will not load filament correctly. My second slot states that it is unable to feed filament into the extruder. My fourth slot makes a "grinding" noise as it fills filament into the extruder. During this grinding, it will stop filling after about every 20 minutes, give or take.
What do I do here? I've taken the thing apart to make sure that there is no filament in any of the tubes. I can take a long piece of filament and run it all the way through the AMS without issue.
This problem happens no matter if I use bambu filam
