Thanks Mike, I'll check into this some more - seems like very good info ( I'll see if I can get my friend to help - I've run cnc's for a while, but new to figuring out what makes them go - onsite, real time help will be a huge plus, and might save me from catastrophic mistakes). I always intended to post more, but since I didn't have any real resolution, or even progress, I thought I'd wait. I guess I should've been more impatient - I'm getting some good info. Thanks again, Alex
