Findings
My personal opinion is that the casting of the focus unit was flawed, picked up on inspection in the factory, reworked and passed as ok.
However, when a JMI motor focuser was fitted by myself and Dennis, damage probably happened to the gears when trying to move the tube against whatever was causing the binding.
As much as I tried to convey this probable scenario to Takahashi, the message just did not get through.
However, as the casting has not been replaced, the flaw still exists and when I receive the unit next week, I will test it out. (maybe Lewis would like to be there to assist)
If the focuser still binds with reducer and camera loaded, then I will take the matter further with Takahashi.
regards,
Phil
