stevesp it moved 60° showing 0° and the it tried again of additional 60°
This sounds suspiciously like one of the slew speed of the mount is wrong.
Try resetting all the speeds of your mount back to the manufacturer's default speeds using the hand controller. The default speeds should be documented in the mount manual, otherwise check Google.
The algorithm (from watching the command packets that the ASIAIR sends to my mount simulator) that ASIAIR uses is flawed.
ASIAIR first selects the slew speed to some slow speed and then test to see how much the mount moves by timing it. Using that movement per amount of time, it (here is the bug) then scales the time to move the mount by 60 degrees whenn using the full slew speed. It assumes that these the two speeds it uses are the manufacturer default, and have the correct ratio. If either of those two speeds are incorrect, the mount will either move too much and crashes the OTA into the pier, or move so little that you don't see it moving at all.
ZWO assumes too much. And if your mount is not set up precisely to what their coders expect, PA will not work.
The solution is to set your mount to what ZWO expects (i.e., the mount manufacturer's default speeds).
Before doing the PA sequence, ZWO could have use the mount commands to set the speeds to what they expect, but they are too lazy to do it.
Of course the mount firmware is the latest version
Not related to firmware version. The algorihm that ZWO uses has not changed -- that is why it continues to work for most people who have the correct slew speeds. The different speeds of your mount needs to be reset to the manufacturers default.
