Mirrored image in mach 3

I’m really sorry if this has been covered already, but I just designed a sign in fusion and created a tool path. I went out to the shop to cut it out, but after I loaded the g code in mach 3 the image is mirrored and upside down… I’ve designed and cut out hundreds of items, but this is the first time this has happened… and it just so happens to be an item that I have a deadline to get it finished… anything will help. Thank you in advance!
