Cabinetcraft,
What quilting machine do you have, which sewing machine rides on it? As I said earlier, and I probably misread what you said in your post, as it appears that you are wanting to computerize a manual quilting machine. That is exactly what I have done. My wife has a Husqvarna Viking machine on a Grace Quilt machine frame with a 24 inch width. The table is 112 inches long. I am driving the system using two NEMA 17 1.8 degree steppers bipolar. I designed a cable system using 35 pound test polyethylene covered stainless steel fishing wire that I picked up at the local fishing store. It works very well and pulls the carriage very smoothly on the table. I am using Mach3 for the controlling software, set at 1/8 step, 800 steps, with a resolution of .05. It may be possible to get better resolution by changing the pully wheel on the stepper on the x-axis to a smaller wheel. 1/1 would be the best but you know how that goes, you use what you can get and then do the math to change it. How is the project going now?
