My printer is flyingbear ghost. LCD controller writes current print state to SD card to allow resuming if power fails. It is constantly writing data to SD card to record print progress. Problem is that its not doing it very well. If power fails, gco file gets corrupted and if you attempt to print it again, it will most likely drive hot end where it does not belong creating problems and even breaking the machine. Any help with that ? SD card write protection switch is not helping. Controller is cheap and does not check that by design. Firmware hack maybe ?
