Every new problem in design should be solved first. The new ideas of the printer must be based on his experience. As the problems are raised and solved, the printer is gradually applying them to the embroidery or the function of the machine. Such as: color change, tension adjustment, carving holes, hole cleaning, embroidery speed or other functions that may be needed. It is also necessary to explain the design he made, straighten out the order of embroidery, add needles or reduce needles, and compensate if necessary. And these can only be achieved by experience.
