Hey Dave,
Thank you for the explanation. I think you should post that explanation in the WIKI because it is so good and there really isn't any real specific info on it there!
I think the problem I was having was I was entering a negative (-) value in the backlash box. I'm going to change that and try again based on your post.
I think that I'm going "give it a rest" for today though. The frustration level meter is starting to peak and I think it's good to take a break when that happens

I'll let you know how things turn out tomorrow!
Thanks again!
Sid
