Creality 4.2.2 #78
Description
I want to convert an Ender 3 into a laser engraver. I have a Creality 4.2.2 motherboard. I tried building grbl in STMCubeIDE. I'm not sure if I did it correctly, but the only thing I changed was uncommenting a line in my_machine. After inserting the SD card into the printer and running it, I no longer had Marlin on the screen. However, when I connected it to my laptop, Lasergrbl couldn't connect to the printer. Does anyone know why this isn't working and whether my plan of connecting the laser to the fan makes sense at all?
