Greg,
About 3 weeks ago my mount during excellent tracking and PHD2 guiding for 15 or 20 minutes would just stop tracking and return to home position for no apparent reason
It did this a few times but not during consecutive imaging sessions and I tried everything to find the problem
Since then I’ve done the following -
1/ Upgraded from Windows 10 Home to Pro ( mainly for my new Dome on the south coast so I can use Remote Desktop )
2/ Disabled Limits in EQMOD ( so mount will track past meridian) recommended by Cloudy Nights post if your having problems with sudden tracking failures
4/ Make sure I plug the mount USB cable into the same physical port on the Laptop and check Com port assignment and connection each time
5/ Make sure I open and connect Apps in same sequence each time and most importantly connect “dither function” in APT before I connect PHD2 camera and mount
6/ Disable Power Management ( Power saving ) of Hubs
Here’s where you can find item 6
Right click Computer
Left click Manage
Double click Device Manager
Double click Universal Serial Bus controllers
Double click Ist USB Root Hub ( USB3 )
Go into Power Management and uncheck “Allow the computer to turn off this device to save power”
Open any other additional USB Root Hubs and do the same
Press OK and close all Windows
So far after another 4 imaging sessions of 3 to 4 hours I’ve had no issues at all and mount has tracked and guided beautifully all night using 2.6.9 Dev4 Multistar guiding
Don’t know if the above is of any help as your probably fully automated ?? But item 6 would be still relevant
Cheers
Martin
