I am trying to do a Temperature calibrate on my printer i Creality Print 6. I load the model but I get this warning message when I slice it " It seems object temperture_tower has floating cantilever. Please reorientate the object or enable support generation". It wont let me ignore it and save the gcode. If I enable support it blocks out the entire model and I end up with a solid plastic brick. What is causing this and how do I fix it
