There are so many things to consider. Are you happy quilting with the King Quilter on your frame without the Qbot? If so, maybe the solution is to sell the Qbot. If not, why not? Is it the frame, or the machine, or something else? Do you feel comfortable quilting without robotics?
Will the Qbot work with the King Quilter if you get another frame? Have you researched other frames to see if there's one that will fit in your space?
