It may or not be the solution to an intermittent problemI have had since last summer, but I found a fault and fixed it !
I was getting occasional "Arm not found" errors which required a cold reboot of the PC
Getting a bit fed up so checked out all the cables that wander through the arm, on the basis that they could suffer metal fatigue
Guess what ! The blue wire was broken internally, just as it entered the top of the end of arm spindle.
I couldn't get a decent picture, but here is the best I could do
the ends look as if they have been slightly rounded by physically rubbing against each other
I replaced it with a bit of similarly sized black wire so maybe, just maybe I have fixed the issue..
a couple of boards just ran through as sweet as a nut.
