Being a bit of a cheapscape I have never used Coral, I use Inkscape, which works perfectly well for designing stuff to be sent to the laser, there are lots of tutorial videos out there to help get used to it. I understand someone has developed an Inkscape plugin which will open the file being worked on, in Lightburn, but I haven’t tried it yet.
