I’m having this issue right now with mine. I just got my A1 and I ordered 4 rolls of refill pla and the one loaded at the back is getting pinched into the edge of the spool by the tension from the ams lite pulling the filament. I keep getting error messages and I have to go pull it out. Its really frustrating and I’ll have to stay up until my print finishes to keep an eye on it. I’ll try this massage thing on it tomorrow and se if it helps.
