This is unrelated to my other issue. However Every now and then the audio starts glitching like slows downs and the bar by the INT REL ABS buttons starts moving to the left. After swtiching into INT to clean the needle it goes back to normal. However this happens at least once every gig I do. Why am I having so much dust on my stuff when they are always on cases? Is the needle carving into the record? Do I need new vinyls? Or is this something that happens to everyone and they are just premptive about it.

Dust will accumulate on your needles fairly fast. This is normal.
I suggest getting in the habit of cleaning off your vinyl every 6 or 7 mixes with a velvet pad and look at the needle for any dust bunnies.
