Hi, thanks for your reply, 
Sure I did the calibration, and that seems to work, but I can't then move the current position.

Moving Absolute position:
2021-05-08T12:28:46: [INFO] Focuser is moving to position 2000 
Moving relative Position:
2021-05-08T12:26:18: [ERROR] Requested position out of bound. Focus minimum position is 0 
Calibrazion:
2021-05-08T12:26:11: [INFO] Setting current position to 0 

Moving Absolute position, is moving the focuser (relative position not) but never complete the command (stay yellow).
I don't know which is the correct model to use in my case.

When I change the Model of the focuser (to test others), Ekos disappear./kill... 

Is really a strange behavior.
