Luck smiled upon me today. Long story short, an incredibly nice person GAVE me a CGE. I was about to buy it from him but he offered to just give it to me because he could not sort out an issue on the RA motor.
DEC is fine.
The issue: It sounds as if the RA motor is struggling. I've tweaked on an AVX before. I know that if the housing assembly for either motor is too tight, it causes the worm gear to bind and makes the motor strain. That's very much what this sounds like with the CGE. I figured out how to loosen the motor and add a couple of shims. That did not seem to make a difference.
Thoughts on what I could do here?
Since this unit was given to me and I have the money in hand that I was going to use to buy it, I've kicked around the idea of sending it in for a hypertune from Deep Space Products. Thoughts on this?
If anyone here is in the Austin, TX area and knows how to work on these bad boys, I'd love to meet up. I'll buy pizza, beer, whatever!
