As mentioned, I know nothing about Lightburn, but saw the video and though it was so well presented, it was worth sharing especially to those just starting out or considering.

There is a lot that the laser can be used for in the workshop, however, if you consider buying or already own one, try to sacrifice those extra shekels and aim for one with a cutting capacity of at least 3.175mm (preferably 6.35mm)... it will extend tour laser capabilities exponentially.... those awkward routing templates that takes time to create manually are only a few minutes print/cut away. 

If your first cut is too short... Take the second cut from the longer end... LBD
