Again about the rotary A axis... As I see the Mach didn't calculate shortest patch and every time uses positive direction. This is in absolute mode, because I don't use incremental and never tried. Also better will be if A axis knows negative digits. Something like this... Zero position (and machine zero) is Y axes on the circle. Possible values +180 to -180. Operators decision go trough 180 or not by check box. In one case calculates shortest patch via 180 in another, change direction regarding machine possibilities.
----- EDIT----
Exactly, Mach 3 behavior suits me. Positive value rotate CW, negative CCW. Will do in post-processor all rest.
