mjcaike55 I have the same issue when doing Polar alignment the slew to 60 degrees takes about 3 minutes.
Next time, see if you can catch it while it is doing the slow movement. Stop everything and take a look at the slew speeds in your hand controller. What are the two fastest slew speeds set to?
From my observation of the behavior of the ASIAIR, it uses the second fastest speed to test how much the mount has slewed after n milliseconds of slewing at that rate. It then assumes that the highest speed and next highest speed has a certain fixed ratio. If that ratio is wrong or one of those speeds are wrong, you get completely bogus and erratic behavior from ASIAIR. (Rube Goldberg would be proud.)
With other mounts, ASIAIR assume that you have not changed the slew speed from the factory default. I don't have a GM mount, so I don't know if Losmandy has a published factory default for the slew speeds, or if ASIAIR knows about it. If you can find the factory defaults, you might want to try resetting all the slew speeds to their factory default values through the hand controller.
ZWO has never admitted that there is a bug, much less hint if they even plan to fix it.
You might be able to experiment with different slew speeds in your hand controller, but be aware that it is not just the higest speed that determines the movement. Check the second fastest speed too, and perhaps others. In any event, stand right next to the mount, ready to pounce on it to stop any movement, in case it overshoots when the ratio of speeds is not what the ASIAIR expects.
