I just got a used Corotor II and hooked it up on the bench with my ASC 1. When turned to Horizontal it lines up to a probe support, but at Vertical it is off by about 10 degrees. When it stops a little short the servo motor continues for a brief moment even though the probe has stopped. That is probably the distance that is missing. I can then advance the probe with the ASC1 and it looks right at about 55 degrees.
I plan to replace the servo but want to make sure that there is nothing else to consider.
