What was the learning curve on the butler? I currently have a Qbot and the learning curve is steep and the robot has to be fiddled with to make it do what I want. Also not exactly inexpensive plus mine runs on wires. Does the butler use belts or wires? Does the butler accept designs from quilt design programs easily? As I have Pfaff Quilt Design software and like to make my own designs. How do you transfer purchased designs or designs from a pc to the butler? Any help would be appreciated.
