How to change the sewing machine of electric flat car into embroidery machine, and what accessories do I need to buy?

If the computer is flat, this one is ok, which requires strong hands-on ability. Computer flatbed has a single-pin button, but generally there is no external interface, so it needs to be wired by itself. There are two sets of stepping motors and sliding tables, and a workbench designed and manufactured by ourselves is used to move the cloth. Next, I need something to drive them. I have money to use raspberry pie, but I have no money to make a single chip microcomputer. Next, the upper software is developed by computer. The basic task is to convert the image into the code of the sliding table and the single needle of the sewing machine, which is similar to the G code and transmitted to the single chip microcomputer for control. This can be achieved. Generally speaking, Xiao Bai is cautious and involves too much professional knowledge, including single chip microcomputer development, software development and mechanical design. If you count your own labor costs, it is simply sky-high. Of course, if you are interested, you can apply for a patent and sell this set as a commodity. It is estimated that the market is also good.
