Just bought a lot of pla refill spools during the sale. First one i opened i did everything by the book when installing it but it is completly impossible to “massage” it since they have put some cind of glue on the filament, one side i was able to massage out but the other side of the spool it sems like the have coated the filament with something that glues it togheter so i cant make it fill out the gap on that side. very irritating and i sure hope not all spools are like this… Get stuck in the AMS al the time and very poor print quality as well so im almost suspecting that they have a lot of moisture or something in them aswell.
