Well, the engineer in me took over and said "Do something now!"... so I did.
Placed an 1/8" nylon washer at the end of the rod... resulted in a nice hard stop rather than a soft one I was experiencing manually. As the focuser has a lot of torque, I was concerned that it would go past the screw and drop the mirror.
As an FYI, stop to stop is just over 42 turns. I read that the best way to calibrate the focuser is to run it in half way.
Wish me luck, about to calibrate.
