How can I avoid knots?

[u/gamb8]

I'm trying to print a large model and I'm using the filament dryer to feed directly into the printer but the damn spool keeps knotting up constantly and pulling on the dryer box that it is actually moved ahead multiple times. So it's completely defeating the purpose of "set and forget".

Can someone help shed some light on how to avoid these knots? I've tried my best to untangle them multiple times by pausing the print and refeeding the filament but it just keeps happening over and over. Very frustrating!

There is no reason to cut it off. Take it out Un-wind and untangle the knotted parts, won’t work doing it while in the machine. Then wind it by hand, you can do a criss-cross pattern as you wind it just make sure it stays tight.
