Hi,

I no longer use RepG but when I did, I found if you didn't select the correct version of firmware when saving your print file, the machine wouldn't recognise it existed, could physically see the file on card when in computer but machine couldn't, same when connected via cable.

Down the bottom when it says export file, you will have an option before firmware version ? or after firmware version ? ( cant recall exact numbers ), try changing the firmware before or after version and see if that helps.

Cheers
