XY Axes, Screws have notching effect in the head profile


I titghten up the two small srews on every side from the xy rods, because they got loose with the time.

But now the head profile is notching. I can't loose the screws anymore.

I need a  maintenance to remove the rods and the xy mounts to drill the small screws out.

can you make me a photo and mark screws that causing you troubles, please?


The non-circled adjustment screw on the left (and the one on the other side not in view due to to rail), if you remove those from each block...the entire central XY assembly should drop out.
