hi @Edwin first of all, welcome to the forum - there are some excellent people here that are very knowledgeable (beginner myself and they helped me out tremendously)
this took me a while to work out, so it is excellent that i can pass on the info (what i now do).
i started with cnc so this confused the heck out of me.
camera capture is a brilliant idea but there is a problem with the firmware (the makers are aware), this caused me to stop using camera capture
i now put everything in the top right corner and manually mark the origin in the bottom left of the wood. the software is meant to put everything in the top right (because that is the work area) - hope this helps.
here is a hint i had to work out, tried to do a picture - unlike cnc the laser preview gives you exactly what you will get at the end of the job, an image in greyscale will be sometimes be black and white - but it is nothing to do with making the image lighter. i found best results with the density changed to 3 instead of 7 (if density is too close, it will make the image black), look at photo’s below
