Hello, I have an Ender 6, abs after printing for an hour or so, it just stops printing and the screen goes black. You have to cycle the power to make it come back on. It did it once or twice in the past, and I thought it was just a bad file or something. Now it does it pretty much every time. I tried a new sd card and updated the firmware, and tried printing a different file. Tonight was the first time it did it while I was standing in front of it. I tried to cycle the power, it wouldn’t come on. Just the hotend cooling fan runs. I noticed it will turn on if I leave the sd card out, but the second I even touch it to the slot, the screen goes black. Any ideas on this? Bad sd card reader?
