Hi Can anyone help me, I have a problem with CURA SLICER , when I import a project into CURA it goes onto the plate, but I can’t do anything with it , when it is in pPREVIEW the top right where it should show the profiles, it shows Print setup disabled G-CODE file can not be modified, the envelope on the top left is closed all the time . When I go into PREPARE it vanishes I am very new to 3d printing so I can’t work it out . I have tried to delete it all and reinstall the program but it does the same again. Hope someone can help me proceed. Thank you Mr Williams.
