I purchased my original DSP license on Jan 3, 2018. Because there were still bugs, Oz offered to discount the software. I told him that I would pay full price to support the cause.
5 years later, I am now using the Galvo version as well. I am sure that I will have to invest in the CNC version when it hits the light of day!
Thanks to everyone at Lightburn and the forum for making playing with lasers fun and safe!
