There was a longstanding problem in which the Dome doesn't move when doing a Polar Align until after I press the ABORT button. But I may have found the issue causing it.I just noticed that the INDI driver for the CEM120 EC2 clears the Telescope Pier Side value as soon as I tell the mount to go HOME. If I slew the mount tho a location, the Telescope pier Side is noted. But if I go HOME, it goes blank.
When I Polar Align, I always start at HOME. Thus the Telescope pier Side is blank, and the dome won't rotate. After I note this, I press ABORT in the mount's INDI control panel. But by the time I do that, the mount has moved, and now shows the Telescope pier Side value. This the dome then syncs up after I press abort.
