Hi, I don't know if the other challengers act the same, mine if I activate the 360 degree range restriction, in the angle in which it is at that moment, it becomes a kind of absolute 0 and will never turn more 360 degrees, it will go to one side or the other but will never go more than one turn passing through that point.
On the other hand if I activate the 180 degree range function, it restricts the movement from that degree to -180 degrees from that point, that is if I am at 180 degrees it will turn only in the arc of 0.1 degrees to the 180 and it will look for complementary angles to stay in that arc.
It does this behaviour all the time and many tests, I don't know if it was ZWO's intention, but it allows me to use the rotator more or less safely.
