Only predefined slicing profiles

Custom slicing profile(s) defined

Not all of these buttons will initially be active. Clicking “Duplicate slicing config” copies the current slicing profile, but with a new (draft) name. You may then “Delete slicing config” (to return to the prior slicing profile. Or if you make changes to the slicing profile – via any of the “PRINT SETTINGS” specific settings; see item 13 – then you may choose to “Save config”, saving the now-changed slicing profile under a new name.
