After multiple jams from bulging filaments on two spools I'm getting frustrated. One, right before a job was done.

Is there something I can do to prevent these bulges in filaments from ruining jobs?

What can I do to prevent this from happening in the future before it's a disaster?

He's a picture of one I found using google.

How to catch and fix these on the fly? That would be difficult..

But this is an issue you really should not have.

Could it be an issue with filament storage?

Or is it coming from the manufacturer with these bulges? If so, I would try contacting ( you may have gotten a bad batch? ), or finding a new retailer if this happens often.

I have gone through a lot of pounds of both ABS and PLA and never come across this.
