Hi guys looking for some advice am trying to use lightburn but need to flash the grbl firmware but when i try to do it i get this message.Anyone know what it means.thanks
I’ve done this a couple of times.
To Flash the controller, you should close LightBurn and any other software that might try to communicate with the engraver.
If that doesn’t solve it right away, please post a link to the instructions you’re following and the tool you are using to flash the rom.
Walk me through your steps, maybe a second set of eyes will see it.
