So I am having the same exact issues that sdengraver had in the post link below and I believe that I have the same exact machine. Would love to get the details on how you resolved your issues. BTW, the support from Universal Engraver is atrocious!
Does anyone know where I can find out where to get the grbl version for my control box? The support at Universal Engraver is horrible, they just don’t get back to you and I just bought the darn laser.
