Mine do not really make any sound probably cuz they are so long. But just lightly pressing on them they only have maybe 1″ or 1.5″ dip midway… The old motor mounts flexed in towards the belt a fair amount prior to changing to the new rollers… I never loosened anything off when i switched.
I need to reflash my Arduino with the correct build size… I was getting an access denied issues. Any hints as to why this is happening? The ramps board is attached.
