After converting cut paths, lines shoot out everywhere

Once I have completed a drawing and send it to my cnc screen for cutting, I then convert it the drawing into cut paths. Every time I do this, I have almost all the lines shooting out into infinity and my cnc informs me that it will not cut because lines are out of reach.
Any suggestions please.
Thanks

I would post a picture of your drawing not what's sent to the printer. Sounds if there is a clipping path out with the drawing. I am no Corel expert so you might want to wait a bit longer but would still post picture.
