I'm looking for some insight. Last night while using my AP900 mount, my software was sending the mount to a location in the sky and I could hear the dec axis motor but there was no movement of the dec axis.
When I tried to manually slew the mount via hand controller, it moved ok. And later did slew to other locations.
I am using the ASIair pro system to control the mount
When I grasp the dec axis and try to move it, it seems to be solid with no backlash.
Any insight into what may have happened to the dec axis not moving?
