We have exceptional technicians for our robotics systems Perfect Stitch and Butler that are here to assist in getting those products working as intended. Unfortunately, because our technicians' time is extremely limited and in high demand, they are not able to assist in answering questions regarding the working of your quilting machine outside of our product. For the same reasons this support site is for our products alone and you should contact your sewing machine dealer, sales rep, or manufacturer for questions regarding thread, needle size, bobbin tension, oiling, and all else related to keeping your machine in good working order.
