I'm having a problem with my NexDome shutter. If I don't have any software running I can use the manual controls to control the shutter just fine.
The moment I connect to the Dome Rotator using ASCOM, the behavior change - it can move for about 6" then stop. If I disconnect ASCOM, the manual buttons work fine again. It's as if the software sends a "reset" command to the shutter every few seconds.
More than that - it has the same behavior inside the ASCOM software itself. It will move for a few seconds, then stop.
Finally, both the close and open button in the ASCOM server just "opens" the shutter (by 6"). Neither button will actually close it. The manual close button still closes (by 6" at a time).
