Just updating my post here now that I’ve practiced a bit.
No, you don’t need to change any settings in the Celestron CGEMII mount handcontrol for Voyager to work correctly. The defaults work fine. The go-tos and meridian flips, tracking and parking all work great. -Just make sure you know where to force a meridian flip for your setup. I have mine set to abandon a capture and force a flip at 6 minutes in Voyager. So far all flips have worked great at that parameter.
The weird slew I encountered at that time must have been a date/time or sync issue. Just make sure you have your date, time, and location accurate. I finally bit the bullet and purchased the GPS add on from Star GPS. It works better than Celestron’s because it’s faster. I highly recommend this. It’s just another thing you don’t have to worry about screwing up! -Image offsite with no internet frequently . . .
I don’t calibrate my mount anymore since I plate solve. If your initial parameters are accurate, the first go-to will be close enough to plate solve. After that Voyager will sync your mount and following go-tos will get better.
