Recently Purchased a used G11 with G1 controller
I gave up on using the RS232 interface....it will connect at times others it will not,.
Tried 2 different Apdapters USB to 9 pin, Cable is sound, At the point were I probably
will trade in for a G2. Cmos battery replaced. Was reading 2.75vdc now 3.25vdc
Cleaned all connections with contact cleaner. Windows 7
I have owned many mounts and have stripped down and tuned many, sucessfully
I have been working with the G11 for 1 weeks trying to match RMS phd2 spec of <.9 rms Total
of my former Sirius mount with belt drive with the same payload of 15lbs
Payload 15lbs
guide scope 50mm SSAG Camera PHD2
Polar Alignment within 2 arc min of pole set by drift PHD2
Using ST-4 port for guiding since rs232 flakey,,,
What have I done.,
Put bolts on gear box cases since 2 of the plastic rivets were broken and causing flexure
with the motor to gearbox . Did both RA and Dec Gears look fine visually
Adjusted worms on both RA and Dec so virtually no backlash or end play exist ( a small bit of endplay ovison)
Ovision OPW gear BTW on RA. both work freely by hand but no binding. I used a feeler guage to
set worm spacings on RA and Dec. .030 ra .012 dec
Checked large RA ring gear for any damage....looks great,.
A bit east heavy RA ....
Other than thrust bearings not sure what is left to do to improve guiding performance.
I ran 3 worm cycles guiding output disabled and get about 8 to 10 PTPeak PE on the RA
Number I get PHD2
1.35 RMS RA
.87? ?RMS Dec
Ill post files in my folder soon?
Thanks for any help
