Cura won’t slice object

[Roger_no 0]

I wanted to do a frame test print on my new 300x300mm glass bed, but cura is unable to slice my model as it states the object it is to big! I have turned off bed adhesion. Cura measures the frame model to be 300x300x1mm. If I scale down the model cura will slice when the model measures 298x298mm. But not over that! I have a CR-10 btw! Any suggestions?

Set bed adhesion to None.

 

By default Cura prints a brim around the object to improve bed adhesion. When there is no brim, there can still be a skirt to prime the nozzle before printing commences. Both of these options require room outside your model.

Yes, but i’ve choosen «none» so There should not be skirt or brim?
