Les,
What on earth are you doing with three different CAMs if you - quote - don't know what you're doing - unquote? Don't you think it would be an idea to concentrate on one CAM only until you get to grips with it? Then with that experience tucked away, you can bring out the second CAM and so forth.
There is a lot of knowledge and experience (and help available) on this and other forums. I think you really need to take a step back, concentrate on one task on one CAM at one time, sort it out and then move to the next task etc. You will find the "search" function very useful.
I appreciate that we all have to start somewhere but to admit, after 67 posts, that you don't know what you're doing must surely mean you're trying to do too much too quickly. Don't you agree?
