@7:57, Do you know if the fretting / discoloration on the taper is caused by your tool changer or pull-stud that is too tight? Pullstuds that are too tight can deform the mating taper causing bulging and subsequent movement within the taper!

The pull studs are tightened to the specified torque, but unfortunately the spindle taper of my machine was damaged due to my mistake. This has resulted in the marks you mentioned.
