Re: Problem with mount
Joe,

Re: Help with DEC backlash/jumpy guiding
It has the RA of the Titan, so if PECprep has the Titan listed you can use that. The G11T has the tucked motor on the RA and DEC judging by these

Re: Help with DEC backlash/jumpy guiding
This is meandering off topic from the original thread, but the secondary PE of 42 seconds seems to consistently show up in more than one G11T so I suspect it's an error intrinsic in the design

Re: Help with DEC backlash/jumpy guiding
Hi guys,
The PECprep program has entries for the G11, but not the G11T...far as I

I don¡¯t believe tucked in motors are yet a feature of Titan, so I don¡¯t think that error shows up on existing/current Titans.

Re: Help with DEC backlash/jumpy guiding
Michael, I noticed you included a list of frequencies in PECPrep that included an entry Worm spur gear 31.9 sec.
I have been trying to clean up the G11 T guiding. I bought PEMPro two days ago

Two last comments regarding power sources: We get dew around here (sometimes

Re: California grease
Chip,
If the grease gets to cold, it will slow down the stepper input into the gearbox. Easy to skip steps. The grease (used loosely) in the older Hurst gearboxes was more like a thin glue.

Hi all!
Yup. It's just a 492 system. I replaced the plastic covers with the metal ones at the beginning of 2016 and was thinking, boy, I don't remember those gearboxes being that complicated, Mr.
