Brett,
I created the file in casmate (my CAD prog) exported it to .dxf.
opened lcam seperated layers, then defined depth for block one then for block 2. in Mach you can view them and the layers are offset like they are supposed to be. the inner line is .250 down and the outer is .750 down. then I opened the multipass wizard, when I try to set the cut depths that is where the file goes wrong. All lines end at what ever depth set. for instance if I do for the outer block .750, the inner sets to .750 too, and vice versa if I set it to .250. The wizard doesnt offer the abality to seperate the blocks.
