My 3 week old CR-5 Pro is refusing to read gcode files from any SD card except a old 128mb FAT formatted card. This includes the card provided with the printer containing the manual and test models. Touching Print, after a long pause, the file list is simply blank. I have checked the card, copied all of the directories and files to my PC for safe keeping. Re-formatted and placed the gcode files back. Still no go.
So I tried a small (128mb) FAT formatted card, placing the factory test files there, still nothing. On a whim I renamed a file to test.gcode Then the printer would see it, and I could select it and print it. I tried renaming the file to a different name, test_1.gcode. It fails presumably due to the underscore in the name.
After trying several cards and many files the ONLY way I seem to be able to print is to use that small card and keep file names back to MS-DOS standard 8 character names with nothing other than alpha or numeric names.
As I said I am unable to print the supplied test files from the card provided with the printer.
Is this OLD firmware? or broken hardware ?
OH I can print over USB via Simplify3D or Octoprint.
