Which printer should I select when setting up Cura or Slic3r? Minitoy is not an option. I tried Ultimaker 2 for the Cura slicing program and I got the gcode but it doesn't show up on the machine ...I put the gcode files on the sd card in the main area (as I saw the "heartbox" file was...and the heartbox printed just fine) and then I updated the app/theme....no matter how many times I've tried the files I'd like to print do not show up anywhere! There appears to be no resource out there with a solution nor have I seen any discussions...HELP PLEASE someone???
