I realize that some customers bought one of these without understanding that there would be a bit of a learning curve if they wanted to do their own creating with it. We’ve done our best to make that information available on the forum here, but I do understand that some folks are just not interested in learning to design their own projects.
That’s unfortunate, because they really can do so many things. 
If you decide to sell it, that’s your choice of course, but before you do, you might want to check out the Tips and Tricks section (because designing your own really isn’t terribly hard) and also the Free Laser Designs section here in the forum,where other customers have shared hundreds of free designs for personal use.
