Problem/ Question: _I have been running my K40 with the Laserboard and Lightburn for about a year with zero problems. Yesterday I was running a job and the laser head just froze. I looked at GLCD and it was froze too. I tried to move the head manually but the stepper motors were energized so they were froze too. I powered everything off then on again and restarted the job. After a while everything froze again but this time the LCD screen went blank but it was still lit up. I went to power off then on again but now I get nothing. The LCD screen lights up but its blank. The stepper motors are energized and I still get the USB connection sound from the windows 10 computer but Lightburn wont connect anymore. I was thinking maybe a corrupted SD card, so I got another card and formatted it and put a BU copy of the stock firmware file and config text on it and stuck it in. Nothing happened. LCD lit up no text and frozen stepper motors. This all happened out of the blue after a year of no problems. Nothing at all has changed on my setup whatsoever. I did notice that after I took the second SD card out and looked at the files that it still had the firmware.bin file on it like it didn’t upload the firmware and change the .bin to .cur or whatever. Like the board is not initializing far enough to load the firmware. I have two center lights blinking simultaneously which It never did. Usually those two lights are blinking back and forth but not together. Did my board give up on me after a year of blissful happiness? I have never had anything but perfection out of this board but now I’m sad! Does anyone know what I can try to get my board running again?
