So I received an NT11 in a trade and the eyes were always detecting something. Pulled the eye pipe and cleaned the eyes, eyes function as they should. As soon as I put the eye pipe back in though, they detect something again.
Eye pipe looks fairly good and is very clear where the eyes sit.
Are the eyes in the NT's that sensitive that the slightest scratch or deviation in the eye pipe can throw the eyes off?
I have owned a DM9, DM10 and a DM12 and I have used some pretty hazy eye pipes in them. Any advice would be greatly appreciated.
