While trying to figure out my probe issue I figure I would make sure that the Z-Truck belt is at the correct tension, and clean the rollers and rails good, since noticed a slight drag at one spot when I moved the Z-truck up and down. I noticed when I hit the drag spot, the two prongs sticking out from the board would move. I can stick my finger behind the Z-Truck and move this board. I checked the Maint. and parts Pdf's but I don't see the board, I'm guessing since it is no longer used it is not included in the docs. I've found some photos from Al Who and others but I couldn't tell if there is screw holding it in place.
So how is this board attached and is there supposed to be movement allowed?
I'm also thinking that this loose board could be causing my scanning probe problems that I have in another thread? I started a new thread thinking this is a separate issue.
Attached it a couple of photos of the prongs and what can be seen of the board without taking the Z-Truck off.
