How to reset lightburn setting?

, hello friend i was working well at lightburn since 8 months ago
till i connect it to a new machine the engrave or cut seems to be reverse
for examp;e if i put the graphic on the top of the layer it cut it in the down and it seems reverse like a mirror, how can i reset as it was before??

You need to create a new profile for every laser you want to use. Then you just change the profiles all dependent which laser you are working with.

how can i do this please?
and how can i reset to cut or engrave as i put the graphic in the layer without reverse it
