I feel your pain. Was in a $350. Embroidery class (not counting supples) when my machine acted up. Luckily the store was able to supply me with another machine just like mine. It took 2 weeks for them to locate the problem. They even called the maker for ideas on what was going on. Got it home and worked on piecing a quilt and small embroidery project. Next day needle would not go up & down. Back to shop. Needed further adjustment because of previous problem. But all is well that ends well. It is now home and stitching just like new. Hope the same works out for you. Let us know how it works out.
