I received my license in January 2018. Being one of the early adopters of the DSP version, I was told that I could use it for free because it still had a lot of bugs that needed to be worked out. I had been in contact with Oz and knew of all the hard work he had been putting into the program so I chose to pay for the software and help out his startup company. I received a few extra months on the license as a bonus for being an early adopter.
I am glad that I did because I have been able to do things with my laser that I never dreamed possible! It is also great to see how far LightBurn and company has come in the past 4 years.
Here is to LightBurn and everyone who uses it! Cheers!
