I have been using the skr 1.4 turbo and I love this thing. I currently it with a TFT35 v2.0 and a raspberry pi running Octopi. We running perfectly for about a week now. Left it printing last night. when I woke up, it had stopped 80% thru an 8-hour print. when I restarted the board, the TFT wouldn’t connect to the board. I tried unplugging everything from the board and tried to power it up just with USB. Nothing is getting this thing to fire up. I know SOMEThiNG is working cause I took the firmware I last loaded and tried to reload it via SD card. It did rename the file to .CUR. Any suggestions on what I can do to get back up and running without having to do an amazon exchange?
