Falcon2 Pro X & Y Axis

Hi All,
really confused, I set up my rotary all good, went back to standard and plugged in the cable, went to lightburn turned of Rotary, now trying to start a project and when I do either a Frame or have tried a cut the engraver goes all the way across the X axis then tries to start cutting resulting it the laser head hitting the side, it goes back to Home ok, Have I missed something !
any guidance or suggestions appreciated
Thanks in advance
