Glad to hear your shooter is working well.
One thing I noticed was that you had to push the disc into the wheels. Make sure the disc isn't dragging between the walls after the first set of wheels (i.e. the walls should be >11" apart). This would require moving the left wall to the left a little bit; it looks like the distance between the right wall and the wheels is good.
