I find in the internet solve of this problem. You need change regional settings in your PC. In additional settings of numeric you can change separation between integer and fractional part from coma [,] to point [.]. In Windows7 I don't know how to change it, but in Windows10 it is easy. After this change gcode is running properly. I thing the developers need to fix this bug in software.
