Orca wont generate brims

Hi All,

I have a sv08 and when i try to add a brim to a model (tried in global and objects) it just will not do it. I have tried playing with the brim type, size, and gap settings. All of my models have a zigzag single line under them that i have not seen until I got the sv08. But it simply will not generate a brim. Any help would be greatly appreciated
