Creality Laser Falcon Engraver-5W
I can't get it started Can someone explain to me how to do it? Using the GRBL programme I save the photo to the SD card, insert the card but nothing happens I deleted everything on the SD card, did I make a mistake? The GRBL program I did the update, maybe I did this wrong too?
