Lately, when I press the "Go To"-button in Focus Control, the focus first goes to the new position maybe 45000 to 50000, but then suddenly (in miliseconds) shows the old 45000 position again! Just the In and Out Buttons works correct!

Does the focuser actually move to the intended position and just the display is wrong or does it not move at all?

yes it move and the position goes from the old to the new and then quickly back to the old position!

example: 65500 >> 67100 >> 65500
