What causes filament breaking in the spool?
I got this esun pla and the cardboard spool didn't fit in my AMS. So I printed a spool and re-spooled it onto the printed spool. It was doing okay for the first quarter of the spool (which is the re-spooled spool so it's the last quarter of the original spool) but then I found that the filament was broken into chunks that were between 30 centimeters and 3 meters long.
I suspect that my re-spooler was terrible, but I don't want to gaslight myself into thinking that it was my fault when it might have been just a bad product(keep in mind, I'm happy to know if it was my fault. Then it's a lesson and that's more valuable). Does anyone have any insight?
EDIT.. Thanks for all your insights. I am absolutely gathering that's moisture, but it's very interesting because most of my filament is matter3D and this is my only esun and it all lives in the same environment and this is the only time I've seen this issue. Granted this is the only pla ive re-spooled.
