Hello all, I shame, but yesterday I found solution :)
Problem was with microstep, because I setup it in firmware, but not insert jumper on ramps, because I think default is without jumper :) After insert jumper move is almost excelent, but it is only about tuning feedrate etc.
But point 3) is still actual. I can't measure current (maybe my current multimeter is ...) If I'm correct, current must be measure on some resist, but I still have zero current :)
