This is the only post I see from you on the forum. This is the recommended place to post for help, as well. Emails should really be for other things, or things with personal info involved.
Anyhoooooo, you’ll need to have a bit more patience. The LB crew is very small, and surely stretched in many directions. The people here are friendly as long as you’re patient and courteous.
But yes, “DIY Laser” doesn’t tell me anything important. There are many controllers, and they all have their quirks and differences. People are running different operating systems like Windows, Mac, and Linux. Diode lasers are different from co2 lasers. So to help you the best, we just ask for as much info as possible. If you built your own laser, I don’t see how this should be an issue.
You’re free to purchase anything you like for any reason whatsoever. Your best bet is to utilize the trial fully to make sure it works the way you expect with your laser. That way you’re not out any money, and LB doesn’t have to spend time and money refunding your purchase.
There is certainly a difference in the purchase you’ll make though, depending on whether you have a supported DSP controller, or a gCode capable controller. $80 for DSP Lightburn, and $40 for gCode.
So, hang tight, and I’m certain someone will come by and help you better than I can.
