I have been testing again and I'm wondering now if it's a setting to do with the arc when it moves between points however I still dong get why it's not starting back were it left off? The first pick I pressed stop jogged to the side and then hit go again. You can see the straight line were I did this and it did not return( centre of pic on his wing)The second pic I hit stop the pressed got to zero and then start and it did a similar thing?(going along his wing) Any ideas is it me or the machine?


Ps if there is anyone willing to give me a mach 3 lesson I would be happy to travel a way for it and pay if needs.

many thanks
