Q, I have CURA 4.0 as of just 2 months ago, my new CR-X won't recognize my CURA 4.0 made files on SD card, but does recognize files from past CURA 3.6 (which is uninstalled now). I have firmware (TH3d U1.R2.9b) When I plugin on my CR-10S,updated board with screen replacement using the same SD card and it recognizes all my files no matter the software version. How can I get around this? Go back to CURA 3.6 logically?
