Finished adding 2 axis stepper control to my wife's long arm quilting machine. Total out of pocket cost including HP Touchsmart computer and Art and Stitch digital design software about $4,000. Took 10 days and I had a blast. Smoothstepper and Mach3 made this project a snap...thanks to all who designed and maintain Mach3!!!! Here's a link to my you tube.
