Ive had it happen in both the AMS and AMS Lite. The issue is not the AMS, matter of a fact you can put it directly into any printed without AMS, tried it on 3 of my machines, it always gets stuck. You should not have to babysit a machine. I have gone through hundreds of spools of Overture PLA (mostly matte), with 500+ orders and over 25k in sales in my small 4 printer farm (3 fdm 1 SLA) and i can tell you factually that Bambu filament is ■■■■. Overture PLA is twice as good and is currently like $16/kg (black friday sale). If you dont like plastic spools you can print an adapter that makes it fit into the bambu reusable spools (or print those as well), and it will not jam.
