The core will not accept the file as stated above. Like said use the "B9 Create" for layout and slicing. The B9 Create software slices all layouts at 10 microns. When sent to the core or moved there by USB then u select the slice thickness for that print session (all are multiples of 10 microns, i.e. 20, 30, 40, 50, and 70 microns).
