I realized that the rack on my PRS Alpha X axis on one side is "sagging" and pulling away from the top rail. It does not seem to be effecting the operation at this time but I hear a slight tick when the gantry moves over this section.
The machine is approx. 10 months old and gets moderate use.
How is the rack attached to the rail and is there a method for dealing with this phenomenon?
