Don't know about TurboCNC, but....
G03 is a counter-clockwise arc, G02 is clockwise.
If you dont program an X or Y with G02/3 you might get a full circle, but you would have to program an I and/or J as circle center
G03I-1.0 should get you a ccw circle, 2mm in diameter (I'm assuming metric, as you're in Sweden
The -1.0 means the circle center is 1.0mm from the start point, in a negative direction.
Hope it helps!
