I have had the occasional time in the past where the floating pin would stick on my VS rDNA 30 when I used an atty with a real long post. Just took it apart and popped it back up. Well a few weeks ago it started doing it constantly. No matter what I use. I tried thoroughly cleaning the 510 connection. Even went as far as cleaning on the bottom side of the connection where the wire connects. Still sticks. Is the 510 connection shot??? Don't wanna have to take it apart every time I wanna switch.
