paulagnelli Hello, in some steps, ASIAIR will turn off tracking (end of plan, Meridian Flip, etc.), which is normal. Please don't worry. In some cases, the mount will automatically turn off tracking (Meridian, low pointing angle, possible hit the tripod, etc.).
In the Storage Settings - Autorun Log, you can see whether asiair has actively turned off tracking. I hope this will help you solve the problem.
