@esteban pacheco#56696 I brought the value back to 5 minutes. and the "stop Tracking x min before Meridian" is set to 5 minutes. are those values ok?
You want the first number to be a little longer (at least, not shorter) that when the time the mount itself stops tracking.
Most mounts have some Meridian treatment and has a parameter when the mount turns tracking off itself to keep instrumentation from hitting the pier. Sometimes they are express in angles (like 1 degree before Meridian, etc), and you need to convert that to time, because that is what ASIAIR uses. 1 hour corresponds to 15 degrees.
You want ASIAIR to stop tracking before the mount stops tracking, because that is when ASIAIR will take one final plate to solve for the positioning and camera angle before it stops tracking. If the mount stops tracking before this plate, the plate will have star trails and thus not solvable.
The second parameter ("after Meridian") depends on how accurate your UTC time is, how accurate your longitude is, and how accurate your east-west leveling is. If all those are precise, you can make that second parameter zero, even. However, for example, if your east-west level is off by even just 1 degree, the transit time of the object will be off by 1/15 of an hour or 4 minutes.
If it is off by 4 minutes, the mount will not perform a meridian flip for 4 minutes from he time ASIAIR starts sending GOTO. The ASIAIR does not Meridian flip -- the mount is the one doing the Meridian flip. The ASIAIR simply sends the GOTO a that time, and if the mount thinks the target has transited, it will then do a Meridian flip.
If you don't think you can east-west level to 1 degree error, you need to give the second parameter at least 4 minutes. Otherwise ASIAIR will keep trying, and the mount will keep saying it is on the correct side of the pier and do nothing. And I think ASIAIR gives up trying eventually.
So, if you want to reduce the wait time, make sure the mount is completely level.
That's it. Very straghtforward.
