This month I focused on the physical assembly of the machine. The Pan and Tilt sub assemblies are complete. The chain lengths worked out quite well so I wont have to re-cut any of the pieces. The steppers currently have enough torque to turn everything, but the shooter is not yet mounted and the ball mixer has not yet been tested with balls. So we have yet to see if the steppers will be enough in the end. I found some weaknesses in the design when it came to the Pan mechanism, however when i secured the axle in a second location the mechanism became very rigid. Next month I plan on finishing the construction in the machine and testing shooting balls to see their accuracy. I will also be casting a urethane shooter wheel and see how well it grips the balls.
