Still struggling with the CGX. although alignment is easier with the new CPWI software and by having a web cam fitted on the spotter scope (best thing I've done so far by a country mile!!!).
On rotation, I would hear a very loud rumbling almost grinding sound from the mount. I recall people used to talk about a noise and even record it and post it. Most of the replies were "It's normal for that mount".
Well today I took the covers off and noticed some things with the belts.
Firstly the gear alignment is very poor from the factory and the belt rides partially off one of the gears. I repositioned them best I could but by design, they just don't line up.
I also noticed that if I quickly pressed the buttons on the hand controller to move the motor back and forth, there was a tiny amount of slop in the drive belt.
So I loosened the 3 Allen screws, twisted a screw driver in-between the 2 sections and tightened the belt slightly.
No more belt slop (obviously), but better still.... no more drive rumbling sound.
I'm also hoping that this fixes the weird delays and non responses I get when I try to fine tune the alignment with the software slew controls.
Anyhow, maybe someone else is getting this noise and now knows what to do.
Merry Xmas and Happy New Year to you all.
