So you experienced the same thing as I did. But how can you be sure that the issue comes from the synscan itself and not from the INDI driver?
I have problems using a synscan with an AZ GoTo mount.
Using Kstars/Ekos, when I the system ask to track a specific RA/DEC coordinates point, the 'main control' tab of the 'INDI control panel' indicates (most of the time) :
On Set : track
Tracking : Off
and the mount doesn't move instead of tracking.
Actually, sometimes 'Tracking' is On, sometimes is 'Off'. I didn't find any rational behind this strange behavior.
When 'Tracking' is Off, the Ekos tab indicates 'Mount Status : Idle'
I have the same weird behavior using skychart (carte du ciel).
Has it happened to someone else? Is there a way I can send more information to investigate this issue deeper?
