It's a little hard to remember the details when you are first starting out, but after you do a few projects you'll wonder how you ever thought it was "hard"!
I have a ShopBot, too. One of the "Buddy" models, which as you may know, feeds the material in the x-axis just like the CarveWright does (albeit not via traction belts and rollers). Although we don't need to add an extra 7" to the length of the material for our ShopBots, we do have allow enough extra material to accomodate hold-down screws or clamps to the machine bed (unless you own a vacuum hold down system).
So, there are similarities, and there are differences, between the two CNC systems. I design monthly projects for both types. I do find myself having to "mentally adjust" to each one when embarking on my twice-a-month design process!
