Ok, thank you a lot.

As i said in the begining, i'm ASCOM formatted. B)

The command of my filter wheel it's very simple. "M23" to move from filter 2 to 3. But even setting Ekos to load configuration file on connection, the comand sent when i connect it's M02 (2 it's the filter saved on FILTER_SLOT property) .
CurrentFilter it's 0, i believe.

I'm almost there :)
