I have the identical setup, and I also had trouble with that about 2 years ago. My solution after pulling some of my hair out was to use small washers between the plate in the kit and the body of the motor. If I installed the motor exactly as the instructions showed, the focuser shaft was jammed tightly against the motor's body. Spacing the motor back just about 2mm was enough to free it up in my case. Seems like quite a few people have had this "tolerance" issue with this motor and the 8se focuser shaft. Depending on the small difference in the length of the focuser shaft, you're either lucky or not. You and I were not! I'm glad to see you found a good way to deal with this issue. If I ever pull mine off or move it, I might try your fix when I reattach it. Thanks!
I spent three hours attempting to calibrate the focus motor but, had to stop to prep dinner. After dinner I started once again. This time I removed the motor and went through the installation instructions per Celestron. Again, no luck. Tomorrow, I will try again by installing the original plate as you suggested. Thanks for the video.
Hopefully you will have success. Let me know how it goes. I also worked for days to fix this issue, but since I installed the stock plate, working like a charm. One thing to note, if it works fine, test it for a day and then reinstall the screws with blue Loctite 242. The screw length is not much left after installing the original plate so Loctite is a must.
I just installed the included plate and used 14mm bolts instead of the original 8 or 10 mm screws that hold the plate that came with the scope. Plenty of threads into the back of the scope. Rock solid won't get loose or bind.
