Well, I get it worked.

Focuser move in and out , can reach desired position, abort etc...
Yes, commands are similar to sestosenso2 and few of it I keep unchanged and my driver just a modification of Sesto Senso 2 driver

I need to investigate some non critical bugs , fix it and it can be used.
Also I run in troubles with setting up QT Creators how it described in iutorial... QT cant find stddef.h so I drop it made all changes in text editor, build and install from terminal, then just run test with Kstars

I think the first version of driver will be ready in few days, with basic functions and then I'll add rest of them (like LEDs, Presets, Voltage etc).
Also still waiting for Tprobes so can test how it works.
