Here's a tip to help keep your liner clean and maybe last a little longer.....
Get some LINT FREE material like a CLEAN shop rag(I cut a corner off of a full sized rag), and wrap it around the wire before it goes thru the rollers. It must be dry because you don't want to contaminate the wire. I used some painter's tape to secure it in place, but you could use a clothespin or a zip tie too.
The wire can get a static charge built up in it, and it will attract metal shavings and dust. This helps to keep it out of the rollers and the liner. I change this out every time I change spools.
Not the best pic in the world....but you get the idea.....
