I there, I am not having much luck using the laseraxe software with my engraver as it comes with very little functionality and either times-out immediately or crashes half way through any project only to burn in the same spot for a period of time. Because of this I have done some research into some other software programs available for cnc engravers. For me to use one however (Lightburn), I need to update from the very old 0.8v of GRBL that has come with this laseraxe control board, to a higher version. Was just wondering if anyone has had any success updating the firmware? P.s. I know they state not to flash the board although I am not having much luck with it in its current state and have spent too long trying to get it to work continuously.
