Roland, Et Al:

I noticed on my 1200GTO mounts that there are small screw-on metal covers

covering the ends of the worm shafts of the servo drive units. When

unscrewed, the end of the worm shaft is exposed. The end of the shaft has a

'flat-spot" ground on it as if a knob could be installed there, using the

flat spot for the tightening set-screw.



Is it possible that a manual slow motion knob was intended here?

Kent,



I can't tell you if the flat spot allows a slow motion knob or not but I do

know that when you are adjusting out any backlash, after the adjustment you nee

to turn the shaft to make sure it isn't to tight. With the various speeds on

the hand controller, why would you want manual knobs?

Steve:

True, I didn't really mean I wanted a manual slow motion knob, just that it

appears there is a place for them.

This is used during assembly to set up the worm gear mesh. If you turn the

worm by hand, you will invalidate any PEM settings or Park information that

you have stored (if the scope was parked). Otherwise, there is no effect.

With the system up and running, the motor will try to oppose any motion that

you impart on that shaft, so don't turn try turning it with power on.

Hi Everybody!







We have just added the new 1200GTO Manual to the Technical Support

Section of the website. The main reason that I am announcing it is that

we would like for all of our 1200GTO owners to take a look and adopt

this as their current working manual. The same goes for the current

versions of the 900GTO and Mach1GTO manuals as well.



In the past, everyone has always looked to the manual that was specific

to their particular production run, and while these are still available,

we want to encourage you to use the newer manuals. We have certainly

learned many things over the years, and there is no reason to miss out

on those lessons by using an older manual. Information that doesn't

apply to an older mount will pale in comparison to the helpful new

information that was not available in the earlier versions. In

particular, the current manuals have the latest information on available

accessories, the GTO Servo Motor Drive System, and some valuable

information on polar alignment.



Constructive feedback is always appreciated. These documents are only

good if they answer your questions and help you to get the most out of

your Astro-Physics GTO Mount. Thank you!







May your skies be clear, dark and steady!

Hi Howard,



How about a direct link to the manual, it would make life easier than having

to hunt for it on that page full of info. Thanks.
