It might be worth your time to check-out the Zenbot line of products. They are fast, inexpensive and accurate. The largest table length is a little shorter than what you are looking for, but it might just work depending on your requirements. I personally have the smallest unit offered by Zenbot (Mini) and have been active in using it for several years with little to no maintenance. I don't think you are going to find very many options with a 10" Z travel. Perhaps slicing the model in your CAM software into multiple layers with the eye to recombine would work.
