General Config, have Rotation Rollover chosen and you will then only get movements in one direction if you only call positive commands. For example if at A0 and you command G1A10F200 it will rotate clockwise to that position. If you then command A8 then it will continue in the same direction right round and past the 360 degrees to get to 8. If you want it to rotate the opposite way then yuou would command A-8.
